What Factors affect the resistance of a piece of wire(evaluation missing)

Aim: The aim of this is to investigate how the length of a fit out affects the shelter of it. Prediction: I predict that the longer the tack to rileher of equip, the greater the resistance go out be. This is due to the sentiment of the free locomote electrons being resisted by the atoms in the wire. In a longer piece of wire, in that respect would be more atoms for the electrons to collide with and so the resistance would be greater. The kinship between the wire length and the resistance should be straightaway proportional. This is because in a wire twice the length of another(prenominal) wire there would be reprise the set nearly along of atoms causing the resistance. An example of this would be in a 20cm wire. The electrons would provoke to set off double to distance if it have to go by means of a 10cm wire. This would in turn double the amount of atoms that the electrons would collide with and then resistance would double. Plan: In this investigation a si mple lap will be set up to read the electric potential and certain when the length of the wire changes. The length will bunk from 10cm - 100cm (1m) with intervals of 10cm. The length of the wire will be changed by moving the crocodile press clipping across the wire on a ruler.

We inflexible that the opera hat thickness of wire to use would be 30swg.This is because a thicker wire would cause too much heat, and the resistance of a hyperfine wire would be high and difficult to measure. The source for this is that a thicker wire has less resistance, because there is more board for the electrons to travel through it. We did preliminary tests to ensure tha! t the wire did not get too hot, and how many cells to use in... If you want to get a full essay, order it on our website: BestEssayCheap.com
