Factors affecting the resistance of a metal wire The problem I am going to investigate the factors affecting the resistance of a metal wire. Factors * The length of the wire. * The material of the wire. * The cross sectional area of the wire. * The temperature of the wire. * The tension of the wire. * The amount of coiling of the wire. Factor to be investigated I will investigate how the electrical resistance of a wire changes in relationship to its length. Hypothesis I predict that the length of wire will affect the resistance of the wire. I think that as the length of the wire increases so will the resistance. I suggest that different lengths of wire will have an affect on the resistance due to the more resistance encountered when the charged particles that make up the current collide with other fixed particles in the material. I also believe that the rate at which the resistance of the...
