Investigation - Factors effecting current flowing through a wire Aim - To investigate one of the factors effecting current flowing through a wire. Factors - * Length - The length of a wire affects the resistance. The longer the wire is, the higher the resistance, and so the current in the wire is lower. This is because in a longer piece of wire there are more particles. It is harder to pass current through many particles than it is just a few. * Diameter - As diameter increases, current increases. To explain this I will use the model of people going through a door. If the door is small, it will take people a long time to get through it. If the doorway is large, it will take the same amount of people a much shorter time to get through. This is the same as electrons moving through a wire. * Temperature - When...
