NAME: Physics coursework Investigating the effect of length on the 7 ~PLAN~ For this investigation, I first decided to list all the factors which I think may affect the resistance of a wire and the reason for their importance. These factors are: * Material of the wire - If the wire is a conductor, more electric current will flow therefore the resistance would decrease, copper is an example of a good conductor. Insulators do not allow the flow of electric current which means the resistance will be at its peak. * The length of the wire - The longer the conductor, the further the electrons have to travel, the more likely they are to have collisions with metal ions and so the greater the resistance. * The temperature of the wire & surroundings - As the temperature increases the metal ions vibrate more (kinetic theory) leading to more frequent collisions with the electrons and...
