Agrana Essay
The Austria-based company, Agrana was founded in 1988 with trading operations consisting of the deed of starting line and stiffen. While relatively lessened, the company only operated two starch factories and three sugar factories. As the years passed, the company has besides concentrate on the outturn of payoff preparation, growth juice concentrate, and ethanol. The sweet stock strategy has en adequated the company to not only grow, scarce expand across multinational borders while increasing the number of buyers to whom they supply their goods and services to.In this paper, an analysis on Agranas emergence will be discussed from an industry-, resource-, and institutional-based view. The challenges in which AGRANA might face as it continues its expansion into sweet(prenominal) regions, such(prenominal) as East Asia will also be a topic of discussion. Since Agranas beginning, the industry has been quite challenging and emulous. Prior to European consolidation in 1989 , the company had to operate on small economies of scale. Many markets in other countries were not open to outsiders, therefore limiting the scope of customers to only local anaesthetic buyers.When applying Porters Five Forces Framework, the industry consisted of fierce rivalry from large competitors, threat of substitution, little to no differentiation which increased the threat of potence entrants, high bargaining power of its buyers, and low bargaining power from suppliers. However, with the integrations of the European Union (EU) and the Central and Eastern European (CEE) in 1989, Agrana was able to contend with larger rivals and expand to markets in other countries. The regional and global integration allowed Agrana to aggressively expand its foreign direct investment (FDI) throughout CEE (Peng, p. 82).This pass increased their economies of scale. With their new profound strategy, the company was able to improve the property of its products as they pursued and formed partn erships with larger buyers like Coca-Cola, Pepsi, Nestle, and Danone. As they puddle continued to grow, Agrana added to their production by focusing on fruit impact and through the acquisitions of other companies. The growth of Agrana is quite impressive as you mean how small the company was, their limitations, and how little they had in order to compete with their rivals. notwithstanding these disadvantages, Agrana capitalized on its resources and capabilities through the improved manufacturing of high-grade products at competitive prices and by a strategy that promotes expansion. Prior to their emergence, the company had little entertain in its resources, no rarity in its industry, wide-spread imitability and no competitive advantage. The VRIO Framework for Agrana was in need of help. Through restructuring, and increased profits, Agrana diversified by adding a fruit processing division.With fruit being a complementary good to sugar and starch, this move fell in line with the b usiness strategy and production already established. To further their diversification, the company turned to acquisitions of companies in the fruit industry. mingled with 2003 and 2007, the company acquired Denmarks Vall Saft Group (fruit juice concentrate), Austrias Steirerobst (fruit preparation and fruit juice concentrates), Belgiums Dirafrost (fruit concentrate) Ger some(prenominal)s Wink Group (fruit juice concentrate), and acquired a 50% stake in a joint venture with Xianyang Andre juice Co. Ltd (fruit juice concentrate) p. 384-385.The legion(predicate) acquisitions have not only added to its growth but its value as well as the company had gained access to numerous markets in various countries. The competitive advantage of Agrana is a result of the value added by its acquisitions and their integration, market knowledge, global growth, and their means of finding new ship canal to develop other products such as biofuel. An institution-based view is a sentiment that argues th at in addition to industry- and firm-level conditions, firms also need to take into account wider influences from sources such as the state and society when crafting strategy (p. 3). This includes formal and informal institutions contact laws, regulations, cultures and ethics. Early in Agranas existence, much of its challenges were a result of the restrictions fit(p) on Western European companies to enter CEE markets and the EU. The opening of the CEE markets, in 1989, presented new opportunities for Agrana and others to expand regionally and internationally. FDI proved to be effective in CEE countries as it lead to be increased profits, production and growth.As stated earlier, Agrana was able to produce goods for major companies allowing them to better cater to the expanding needs of its corporate buyers (p. 382). As the company reduced its challenges, the EU encouraged the company to diversify its operations in order to grow. Though the EU imposed challenges for Agrana prior to its integration, many of the CEE countries have become members which have helped the company increase its opportunities.However, with a intemperate EU presence in sugar reforms, regulating prices, and tariffs on imports and exports, Agrana has encountered new challenges and looks for new opportunities. Currently, Agrana has a huge presence in most European countries as well as plants in Mexico, mainland China, South Korea, and China. Though China and South Korea are countries of East Asia, further expansion into other regions may present challenges surrounding culture. A presence in North Korea is cold from foreseeable and while business in the CEE is similar to Vienna, Austria, the culture in East Asia are hugely different.There will also be challenges when you consider how Agrana plans to duplicate its European working environment in countries where employees and attention operate on more of a hierarchical management entitle that stems of culture and tradition. More important ly, the biggest challenges that Agrana will face will be colligate to the laws and regulations of the local government. Each country has different laws and regulations regarding imports/exports, employee relations, production, working conditions and acquisitions.Agrana will also face challenges in competition presented by local companies operating in similar industries. Agranas rise to dominance starting a small company is similar to the story of Google, Inc. With strict limitations and an overwhelmingly grounded industry, the company chose to confront and capitalize on the opportunities presented. Through FDI, restructure, innovation and expansion Agrana has gained a competitive advantage in its industry. Their business strategy of this company is one to wonderment over and imitate.

Characteristics of Orsino in Shakespeare’s Twelfth Knight
Characteristics of Orsino in Shakespeares Twelfth Knight chicane is desirable, everyone is in search of it, but some take it too far. roughly let it control you, and reveal characteristics that ought not to be revealed. Orsino, in the one-twelfth knight for example lets fill in control him uncover aspects of his personality that reveal is obsession with get it on. Some Notable Characteristics of the Duke of Illyria are his moodiness, selfishness and how he is a blast for love.Orsino is a gentle gentlemans gentleman who is in search of love, and duration eagerly searching his moodiness and rattlebrainedness is revealed. Struggling to palpate love, Orsinos glowering moodiness is revealed. His moodiness is revealed early in the play when Orsino interrupts his own symphonyians while they are play to satisfy his needs. Orsino has musicians playing around him in hopes that it will distract his thoughts from how bighearted he wants to get hold love. Orsino says, Enough no more Tis not so sweet now as it was before. (Act I, delineation I) This reveals Orsinos moodiness because the musicians were only nerve-racking to cheer him up, and Orsino deliberately and rudely interrupts them because the music was doing no good in hopes of cheering up his lonely heart. Also, later in the play Feste take down points out Orsinos moodiness. Feste compares Orsinos erratic moods to a gemstone when he says the Dukes thinker is very opal. (Scene II, act IV) An opal is a gemstone that shimmers and shifts in colors.Although, this is not meant to be a compliment by Feste, Feste is rather implying that Orsino is temperamental and unstable, like an opal evermore shifting in colors. Although, for Orsino, unlike an opal constantly shifting in colors, what shifts constantly is his moods. Orsino is a man who is more fixated with the fantasy of love than the reality of love, which portrays his selfishness in just wanting to fulfill his own desires. Orsino seems to be a man who is in love with the idea of being in love.The play begins with Orsino saying, If music be the food of love, play on Give me excess of it, that, surfeiting, The relish may sicken, and so die. That strain again it had a dying finalise O, it came oer my ear like the sweet sound, That breathes upon a bank of violets, thievery and giving odour (Act I, Scene I) Orsino is very fixated with love, willing to do whatever it takes to satisfy his own needs. He is so willing he crimson attempts to puzzle love in a woman in which he discerns doesnt feel the same about him.Orsino fights to have Olivia love him back, in fact the more Olivia rejects him the more it seems Orsino tries t pursue her. Orsino doesnt administer that she has no love for him back, he just wants to find love, and thats the selfishness indoors him. Orsino is a man in search of love, so determined to find it he makes a fool of himself. Based upon the opening scene we get it on Orsino is a passionate man who is out in search of the love of Olivia. Orsino says he is in love for the countess, but Orsino doesnt truly know her, he just knows of her.When Orsino describes one of his fantasies, you can determine from it that it has nothing to do with the countess. The first time Orsino saw Olivia he describes, That instant was I turnd into a hart And my desires, like fell and cruel hounds, Eer since pursue me. (Act I, Scene I) Orsino says he was turned into a hart (a male deer and to a fault a play on the word heart) and that he was track or hunted by his own desires, which were like hounds. So, Orsino doesnt imagine his quest of Olivia so much as he fixates on his pursuit of himself in a fantasy that is all about him.He is a fool for love, fixated so much around it that he tries to make himself believe he is in love with someone he truly doesnt nevertheless know. Orsinos moodiness, selfishness, and foolishness all revolve around what means the intimately to Orsino, love. His moodiness flares up w hen dealing with the problems he faces when move to find love. Orsinos selfishness is revealed in the way he pursues a countess that doesnt love him back, yet doesnt even know him. Foremost, his foolishness is revealed by the way he tries to find love in general.Revolving so much around trying to find love, that he goes to extreme measures that makes him look foolish. In fact, anyone trying to find love as hard as Orsino should be looked at as foolish too. You cannot force love upon anyone, and you should never force it upon yourself, or you will be compelled as selfish in the fact that you want love so bad you do extraordinarily selfish things to do so. Like trying to love a woman who doesnt love you back. Love is something that cannot be forced, that Orsino apparently doesnt know, causing him to be moody, look selfish, and be a fool for love.
Recruitment and Selection Essay
The hiring address arse be draining and drown out. Searching for the right nominee to fill the position can be comp ard to finding a beset in a hay stack. Many employers commit an idea/ opthalmic of how the replacement of what qualifications the new-sprung(prenominal) employee should acquire before the training process tamp down place. With employee selection, assessment and decision devising process should be c atomic number 18fully assessed to batten that there are no laws broken were potential law suits can be filed.This paper willing discuss the legal issues that whitethorn come out if the above processes are not handled with precaution. Legal Issues With the ontogeny of lawsuits that are existence established in the workforce over the past years they film been an increase in the number of attorneys and firms that specialize in employment law. With the sparing in the shape that its in, more(prenominal) companies are having to law sullen employers, roughly that squander been there for years. Their selection process is being questions on how they are choosing the employees that are to permanently/temporary laid off. in that respectfore this is sufferd an increase in the number of cases the firms are taking in more cases at least 15% more than the previous years. This is because many feel that employers are firing those that can benefit from staying employed and receiving their full benefits, in most cases retirement. To decrease organizations from being forced to participate in lawsuits brought about them, an expression stated the best alternative would be to develop a dodge for the participation that involved at least three of the following locomote1) Draft good policies and revise them frequently ) Train employees to follow procedures utilizing scenarios that urge open discussion, development of issue awareness and recognition of employer and employee responsibilities 3) Insist on effective consultation and communication among mana gers, human resources professionals and legal staff (in some new(prenominal) words, the team approach) (McDowell & Leavitt 2011). Discrimination Issues The process of hiring new employees for a position at bottom an organization. With this process, the major legal issue that the employer needs to keep in creative thinker is not to discriminate.Discrimination is a big factor due to the employer has in sound judgement what it takes for a person to perform the duties of a certain position. There are several laws that the organization must keep in their mind when screening employees, such as the Civil Right Act of 1964, disability Act, Age Discriminating Act, and many more. Each of the acts and laws prohibits employees to discriminate against employees or new hires based on their race, sex, disability and religion.In todays time, employees start out to have a firm or an attorney working for them to look into that that they are not breaking the as many With given employees asses sments, roughly employers are given them the assessments to point out their skill sets. But some assessments identify other issues within the employees. Some assessments identifies whether or not peck have a mental illness, learning disabilities, or any other illness that may prevent them from performing their job duties. As a result, many those assessments are being said to discriminate against the employee, thus violating their rights.If an employee has a mental health illness the only way a company/organization can terminate them from a position is if that illness will prevent them from performing their job duties. In fact, many executives stated that they are reluctant to hire people with disabilities due to the accommodations they may need. But with all the baby boomers retiring they are going to have to look into that area. In 2005, statistics showed that 21,455,000 (12. 6%) of the 169,765,000 working-age individuals reported one or more disabilities (Lengnick-Hall, Gaunt, & Kulkarni 2008).Executives were also asked is it a main antecedency to hire people with disability? They responded with the following trying to hire someone with a disability, the main relate is . . . having the skills you would need to be on the air to be able to do those things that would actually apply. I think it would be the perception that people with disabilities acceptt have communication skills and wouldnt be able to problem-solve at a faster pace, wouldnt be able to independently problem-solve (ibid). outcomeWith larger organizations, it will be best to have a lawyer working hand and hand with the human resource department to experience that they dont discriminate against employees. Since discrimination is the major issues within the workforce. It could cause the company millions and most likely close the doors if they dont have enough revenue to pay the lawsuit. Discrimination, especially if the executives of the organization are making statements as the ones is the s urvey, mention that its not a main priority because they may not be able to communicate as others do. Thats a perception and basis.

Teaching Lexically Reflection Paper
Gary Yauri Mayorca November 2012 Lima-Centro ELT Course Reflection Paper Teaching Lexically Having had the opportunity to read various ELT fertilises, I cannot stress how much methodological-insight I gained upon my successful closing of this flesh. What should I emphasize during each lesson-objective? and How will this activity maximize the students learning-awareness? This course made me see that these two questions are pivotal to the development of both lesson plan or didactic material to be used by students.A persons word bank, Lexis, or Lexicon if you will, is the ultimate means to successfully break a language barrier even if with a poor grammar usage (although the bound poor could be argued since it can now be considered not as poor simply rather as the inter language make up between L1 and L2). Why would I be so certain somewhat such claim being based on a champion course? I say this because I lived it myself during my experience in the U. S. s a second language learner, when I had to proclaim with native speakers in order to get by, using lexical chunks that worked effectively time afterward time while most of the time I really didnt ready a keen understanding of each grammatical structure that held unneurotic the chunk of Lexis that I used. How much is this/are these _____? Id kindred to have a/an _____ for here / to go, please How did I know that these expressions were the appropriate ones to use having not had a formal classroom explanation of much vs many or Id like vs I like? he answer, a infixed splanchnic awareness of high frequency Lexis being used in condition right in front of me, most of the time, while waiting in line and listening to those ahead of me having successful exchanges, some other times while sitting on the bus and over hearing language-rich strangers conversations, and one time again taking such and other opportunities to pick up continual random Lexis, thus becoming more aware of the different contexts of different collocations, sometimes used formally, sometimes used in a colloquial manner, sometimes even understanding made-up words such as brunch (a wholesome late breakfast hat more well-nigh resembles lunch time) or I need change to use the _____ vs I need to change _____ (x) so I can _______(y). Nowadays, this approach to the natural discovery of language is supported by strong scientific seek (e. g. The Corpora program) giving instructors new insight on the way students can demote acquire, ( on that pointfore making a more solid attempt at talk effectively with others), making lessons both, more meaningful and engaging to pupils.Having worked with the Word touch series for a year and half, it doesnt really take an up-close look to bill sticker how much of the Lexical Approach is embedded course after course take for example the in-context vocabulary presented at the beginning of every lesson, the pose of useful expressions that can be combined with the previous voca bulary plead for the build-up of lexical chunks which ultimately are to be used at their fullest during the communication activity.At this point, It is imperative to point out that although the book series present a natural inclination towards the lexical approach, the job is not done there but its rather to be taken up by the teacher in order to provide students with the maximum number of opportunities to notice and fix aware of the strong link between Lexis and how people really communicate in real life outside the classroom this way help students develop a more educated language-understanding intuition that can be applied to all four skills, being speaking, listening, reading and writing.Finally, I would like to thank the institution for allowing me and my colleagues the opportunity to further expand our expertise by providing the chance to take these courses at no other cost but the clash of less effective and more effective teaching notions to be reflected on.
Mla Format – Abortion
Jean Lin Ms. Kasababian Language Arts Honors 30 November 2012 Abortion In 2008, twelve women taking resident in the U. S. died payable to effectual miscarriages performed during the aid or 3rd trimesters of pregnancy. Abortion should be unattached to all(a) females living in the United States, but must be a legal citizen to adjudge late stillbirths, which ar during the second or third trimesters of pregnancy. Abortion is a regenerate that women have, and the Fourth Amendment look to and seizure supports it.Fewer women will exercise abortion if it is kept legal in the U. S. deeply abortions are dangerous, so only legal citizens of the U. S. may have second or third trimester abortions. In the 1820s, various ideas against abortions began forming in the United States. computed tomography passed a statute targeting apothecaries who sold poisons to women for purposes of abortion, and New York made abortions a felony 8 yrs later. The criminalization of abortions accelerated t hrough emerge the 1860s all the appearance to the 1900s.Some states did allow abortions to generally protect a womanhoods life or pregnancies imputable to rape or incest. The famous Supreme Court case roe v. Wade in 1973 legalized abortions throughout the U. S. The Court argued that the First, Fourth, Ninth, and Fourteenth Amendments protect an individuals zone of privacy. On Jan. 24th, 2005, Hillary Clinton made a speech addressing her thoughts roughly abortion. Lets defend the right to an abortion while doing all we can to ensure that fewer and fewer women exercise it. The Fourth Amendment, Search and Seizure, applies to a womans right to have an abortion The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be s eized. (Mount 1) Note that the poop amendment specifies that authorities must have a warrant to scour a person of his/her belongings.The baby belongs to the spawn, and therefore she has a right to decide whether to have an abortion (to have a doctor search her) or not. NARAL pro-choice America (National Abortion Rights presention League) believes in keeping abortion legal and safe. NARAL also believes in lessening the need for abortion, which means keeping the admittance to contraception, or birth control, wide open. Even pro-life persons believe in access to birth control. Hillary Clinton stated in her speech in 2005, The pro-life Senate minority leader, Harry Reid, has a bill called the Prevention First Act that would expand access to birth control. Access to birth control does not act in the same way as an abortion does, however. galore(postnominal) CPCs (Crisis Pregnancy Centers) mislead women into thinking that abortions cause breast cancer, that birth-control pills cause abortions, and that abortion can lead to sterility. CPCs do anything to talk a woman out of having a legal abortion. Late abortions are performed during the second or third trimesters. A method of late abortion is a saline injection. This is when a needle is inserted into the uterus through the abdominal wall.Amniotic politic, which is the egg white that provides nutrients for the baby, is dead(p) from the uterus and replaced with concentrated salt water to kill the fetus. The amniotic fluid drained is said to be dangerous if it were released into the womans body. The woman can die, but has a very low stake of macrocosm infected. One idea brought up by pro-life activists is that abortion is murder. fit to the 14th Amendment, people born and naturalized as citizens in the U. S. are protected under the law. A fetus is not yet born.Just because it has a life doesnt mean the fetus is protected under the law. The mother is, but the unborn baby is not protected as an individual. The refore, abortion is not murder, and abortion is not illegal. Everyone, either pro-choice or pro-life, wants to cut down the amount of abortions practiced According to the most recent data from the Centers for distemper Control, since 1990 the number of reported legal abortions dropped from 1. 4 million a year to 853,000 in 2001. The number of abortions for every 1,000 live births dropped from 344 to 246.

Cell Specialisation
All kiosks argon designed to perform a particular trouble within an being, that is, to sustain life. Cells bear become specialized to perform a particular function within an organism, usually as part of a giantr tissue consisting of some(prenominal) of the same carrells working together for simulation muscle cells. The cells combine together for a common purpose. All organisms give make specialised cells. There argon hundreds of types of specialised cells. Below is listed nearly of the major ones found in workss and animals.Plant Cell Specialisation. Guard cells (a twain form a stoma hole) kidney shapes cells that change shape depending on water system supply content. Regulate the exchange of gases in and out of the plant, and the amount of water doomed through the leaves of the plant. Pollen grains circular cells with an extremely hard protective cell skirt containing sperm cells, pollen grains germinate when they come in contact with female stamens, producing a pol len tube through which the sperm travel to r individually the ova (ovary). These pollen tubes move considerably be seen in a corn cob.Root cop cell designed to increase the outdoors ara of the root for absorption of water and mineral nutrients into the plant. These cells have a very thin cell groin that is fully permeable that supports the absorption of mineral nutrients as ions by cation and anion exchange. see to it large vacuoles for the short term storage of these nutrients. Epidermal cells feature a impressible cuticle ( blanket) to help prevent water loss from the plant, the cells on the top side of the leaf tend to be more waxy due to higher exposure to the elements.Palisade cell (mesophyll) designed for photosynthesis, it is a tall cell with a large surface area contained many chloroplasts. Located on top side of the leaf in plants to allow optimum absorption of light and carbon dioxide (inputs for photosynthesis). Xylem and Phloem cells (combined referred to as vascular bundles) cells responsible for the transport of water and nutrients around the plant. Vascular bundles are regain in a ring around the out-of-door of the stem in higher order plants. This provides structural support for the plant (plant can spoil if ring barkedas equivalent to strangulation ).Xylem carries water and mineral ions up through the plant to the leaves. The phloem transport products of photosynthesis to other areas within the plant for storage (growth). Stone cells (sclereids) extremely hard to provide protective covering to the seed in stone fruit. Animal Cell Specialisation uninfected blood cells (phagocytes) part of the bodys immune system, it is responsible for engulfing, faulting down foreign material (bacteria)and cellular debis in the blood in a process called phagocytosis. They are highly mobile, able to endure mingled with body cells.Red blood cells have no nucleus and contain haemoglobin, the molecule that carries the atomic number 8 around the body to the cells undergoing respiration. Red blood cells with a high oxygen content appear bright red, with low oxygen c erstntration dark blue/red. Retina cells the cone and rod shaped cells of the retina are sensitive to light. These cells send electrical messages via the optic nerve to the brain. Muscle cells (fibres) these cells are long and smooth in structure. The flexible nature of the cell allows them to move by contracting and expanding.This contractile ability allows to cell o right away change length. Microvilli (cells lining the small intestine) these cells have finger like extensions to the surface of the cell to allow greater absorption into the cell by change magnitude surface area. Nerve cells these cells are elongated with trendril like extensions at each end, and capable of transmitting electrical impulses along the cell body. These electrical impulses are able to contract muscle fibres and stimulate brain cells. Cilia tiny hair like cells designed to pr event damage to the lungs by airborne particles.Cilia cells make the surface of the nasal passages and secrete a mucas (snot), a sticky shopping center that collects the dust particles captured by the hairs , where it is swept towards the back of the throat and then swallowed. spermatozoan cells designed to fertilise egg cells, they are very small with a tail to allow movement by swimming. The head of the cell contains enzymes that can digest the outer surface of the egg so that the two nuclei can fuse. A sperm cell contains half(a) the number of chromosomes of the parent organism (genetic material from the father), which will be passed onto the offspring.Ovum (egg cell) designed to be fertilized, the cell is large, bulky and not designed to move easily. Like the sperm the ova contains half the number of chromosomes of the adult organism (mothers genetic material). The ova contains a large food store in the cytoplasm, needed for the developing offspring once the ova has been fe rtilized. Osteocyte (bone cell) calcium carbonate and calcium phosphate are deposited around the outside of the cell to form a hard outer covering (bone).
Ohmââ¬â¢s Law Investigation Essay
Hypothesis Because I am using slovenly person electrify as a resistor, when I ontogeny the length of the wire the protection should take to the woods how resistors in series work. This means that when I maturation the length of wire (or add a piece in a series circuit) the electric resistance should increase too. Due to the increase in the reckon of atoms and ions between the two terminals it takes the electrons longer to get from one(a) side to the other. For employment if I triplex the length of the wire the resistance get out double and the veritable leave halve. My graph at the end should look something like thisThe length of wire and resistance should be directly proportionate to severally other. Equipment -2 1. 5V cells -Metre ruler -Copper wire -Voltmeter -Ammeter -Wiring -Crocodile clips Method First I decided upon the typecast of wire I was going to use (copper), I made current it was the same thickness each time I took readings because as aforementioned, if the swing come on sectional area is non kept unbroken, it will definitely strickle the resistance and and so make my results inaccurate. Then I totald it to 100cm by laying it a blow a metre ruler, because this way I freighter be accurate to the millimetre.I then hooked the 2 cells up to the copper wire stretched across the metre ruler using my wires and crocodile clips. I connected the two terminals on the metre ruler 40cm apart. For this experimentation I will take readings for p. d (potential difference) and the resistance using an ammeter and a voltmeter at outperforms ranging from 40cm to 100cm I will take measurements in 5cm intervals (i. e. take measurements from 40cm, 45 cm and so on so forth). I made sure that the voltmeter and ammeter were fall up in PARALLEL not series as this would constipation them. Below is a diagram of my apparatus and how I set it upAnd the (simple) schematic of the circuit In this experiment I will sustentation all things constant (apart from the length of wire). I will lionize do all my measurements in one day in a laconic space of time in the same room away from the windows (out of the sun) so the temperature does not change noticeably while I am carrying out the experiment, as this would affect my results and make them inaccurate. Also, when charge turn tails through the wire and on that point is resistance, it generates heat in the wire. I will keep the power on the wire for the least amount of time and take my readings quickly so the temperature does not affect my results.In addition to this I will in like manner wait a minute after each reading so that the wire coolheadeds to room temperature again and my results are accurate. In theory the graph-line should be straight if it isnt then it indicates that there is another variable. The other constant is the cross sectional area of my wire this is fairly easy to keep constant just use the same piece of wire. I pull in to keep this the same becau se cross sectional area of wire is proportional to the resistance if I do not keep it the same it will also make my results inaccurate.I will take readings from each distance 3 generation and take the medium of those, so I bed greatly decrease the chances of getting an anomalous result. Results Here is the results table followed by a graph representing each of the 3 p. d, Current and then resistance. distance of Wire (cm) Potential Difference (V) Current (A) protection (? ).And finally, to calculate the resistance I used the ohms law formula of R=V/I. Analysis My experiment was very successful and the results I got proved to be quite accurate and precise. Therefore my graphs and result tables provide me with a understructure to understand just why length affects the resistance. My prediction was that when I increase the length of wire the resistance should increase too my prediction is back up by my results and appears to be correct. The graphs and tables prove that the lo nger the copper wire, the higher the resistance.Resistance is also linked to charge flow, if I change the charge flow it will have an affect on the equation I = Q/t. If the current is changed then this will have an affect on the resistance. So with the uphold of the formulae I=Q/t and R=V/I, I now inhabit that if I increase the charge flow, the current increases and the resistance decreases. Consequently if I double the length of wire the equation I = Q / t will be halved (due to the time increasing) causing the current to be halved and the resistance to be doubled.I can see one anomalous result in the Current graph, which is at a length of 80cm it appears to be at a slightly lower current than it should be in relation to the others. military rank Using my results and my graphs I can clearly tell that my experiment was successful, I can tell this because, generally, none of my results have any inconsistent results and my graphs scan straight lines. Even after repeating my exper iment many times my graphs still remained just as precise and the graph showing the average results of the experiment is a perfect straight line.The fact that I got the uniform results each time I did the experiment suggests that is was successful and also reliable, thus I must have carried out the experiment well. The way in which I conducted the experiment was good because I made sure that the potential difference supplied to the wire was equal each time, the cross sectional area of the wire remained the same, and also that the wire cooled down between each result. The use of mm instead of cm made sure that the length was exact and not longer or shorter. Therefore my results were successful and reliable for us to work from.However this did not mean that the way in which I did the experiment couldnt have been improved. Having to secure the wire so as to measure the length meant that it was difficult to attach the crocodile clips to exactly the end of the wire. I could not be sure that as I left the wire to cool it was not at a different temperature each time I begun again this could have affected my results if it had been vastly different. In my experiment, I could also have investigated a number of other things, such as the tack of cross sectional area or temperature on the resistance.If I had looked at the effect that the cross sectional area had on resistance I would probably discover that as the wire doubled in cross sectional area the resistance would halve. This would be due to there macrocosm twice as many electrons the current would travel a cover quicker and thus decrease the resistance. If I looked at how temperature affected resistance I would probably find that as the temperature of the wire increases, the particles within sire to vibrate much more because they have some extra energy, then it is much harder for the electrons to move through and thus the resistance will rise.So instead of just investigating how length affected the resistanc e of a piece of wire I could also have investigated the affect of temperature or cross sectional area on the piece of wire tour Burclaff Page 1 of 10 Show preview only The to a higher place preview is unformatted text This student written piece of work is one of many that can be found in our GCSE Electricity and magnetism section.
