How does the length affect the amount of current flowing through a piece of wire? Aim: To see how the length of a piece of wire affects the current flowing through the wire. Prediction: I predict that the longer the wire the least amount of current flowing through the wire. So if the length increases then the resistance will also increase in proportion to the length and the current will decrease. I think this because the longer the wire the more atoms and so the more likely the electrons are going to collide with the atoms. Scientific knowledge: As a result of the structure of all conductive atoms, the outer electrons are able to move about freely even in a solid. When there is a potential difference across a conductive material all of the free electrons arrange themselves in lines moving in the same direction. This forms an electrical...
