Resis of Wire

AIM Aim is to guinea pig what promoters effect the electrical resistance of cables. The twain factors that we argon studying are diam and distance. We chose diameter and studied. I distinguish open to choose diameter because it has a more complex blood to resistance than any separate 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 testedd temperature as the controlled surroundings needed to get under ones skin accurate and reliable results would be an oil bath. The oil would have to be form creating a potenti solelyy dangerous try with a high level 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= oppositeness V I X R RESISTANCE enemy is how easy/difficult for up-to-date to flow in a circuit, all components have a resistance. You can calculate it using ohms law.

FACTORS THAT EFFECT RESISTANCE A factor is something you can change and it leave change the end result. The factors in our look into will be. Type of admixture Temperature Length Diameter Type Of Metal We only had copper, constantan and nichrome in school these will secure our resu lts. We used constantan as Copper has a rea! l low resistance call backing the results would be irregular. Nichrome has a very high resistance, this would mean the wire would get gamey and we would have been using two factors. How I Made My taste Fair? To make my quiz fair I do sure I was able to control all of the factors of the experiment. 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
