Science coursework. Aim; In this investigation I am going to find out (through an experiment) how much resistance a piece of copper wire will produce when it is used in an electric circuit. Theory; Inside a piece of copper wire there are millions of fixed protons. Electrons are attracted by these protons. These protons may give away one, two or three of the electrons attracted to them as long as they will get some from somewhere else (another set of protons), to make up for them given away. However, whilst an electron is missing from a set of protons it makes a positive ion. In an electric circuit, the power source supplies a "push" of electrons through the wires. The protons layout throughout the wire supplies a "resistance" to the "push" from the power source. This resistance does not allow as many positive ions to be made. To measure the resistance within my circuit...
