Experiment to investigate how the Resistance of a wire changes with its length Planning- Background Scientific Knowledge and Information Resistance is formed when an electron tries to pass through a wire but in doing so, collides with metal ions in the wire. The more collisions there are the higher the resistance, and the longer the length of wire the higher the resistance. It is hard for the electrons to move through the wire as there are so many metal ions colliding with them. Factors Factors effecting the resistance of a wire would be- * The length of the wire because the longer the wire the bigger the resistance. * The area of the cross section of the wire because the bigger the area, the smaller the resistance. * The metal the wire is made from because different metals have different resistances. * The temperature the wire is, because the resistance of the wire changes with the...
