Resis of Wire

AIM Aim is to guinea pig what promoters effect the underground of electrifys. The twain factors that we argon studying are diam and length. We chose diameter and studied. I distinguish open to choose diameter because it has a more complex blood to resistance than any other factor. I also did non use length because the result would be inaccurate, as we would view as had to use the same wire many times. I could not watch mea bona fided temperature as the controlled purlieu needed to get under ones skin accurate and reliable results would be an oil bath. The oil would have to be het up creating a potenti solelyy dangerous try with a high direct of risk. I did not study the type of wire as this would be a fellowship variable, allowing me to only draw a bar chart fashioning me unable to see a clear correlation and consequently making any conclusions I would draw from this data rubbish. OHMS LAW Ohms law(Ω) is V=IR. V= Voltage I= Current R= bul wark V I X R RESISTANCE unsusceptibility is how easy/difficult for up-to-date to flow in a circuit, all components have a resistance. You can calculate it victimization ohms law. FACTORS THAT EFFECT RESISTANCE A factor is something you can flip and it entrust change the end result. The factors in our look into will be. Type of metal Temperature Length Diameter Type Of Metal We only had copper, constantan and nichrome in school these will line our results. We used constantan as Copper has a very low resistance call backing the results would be irregular. Nichrome has a very high resistance, this would mean the wire would get calorifacient and we would have been using two factors. How I Made My establish Fair? To make my quiz fair I make accepted I was able to control all of the factors of the experimen t. I controlled the length in my experiment ! by making sure I measured all of my wires to 45cm so the variable of length was controlled. I made sure I...If you want to get a full essay, order it on our website: BestEssayCheap.com
