Planning The problem that one is being faced with for this investigation is that of; "Factors which affect the Resistance of wires." The factors that affect the resistance of a piece of wire are: * Length * Diameter or thickness * Temperature * The type of metal. The variable I am going to do is the length of a piece of wire. The aim of my investigation is to investigate how length affects the resistance of a measure of wire. My background knowledge is as follows. * Resistance is the force, which opposes the electric current around a circuit so that energy is wasted 'pushing' the electrons around the circuit. * Resistance is measured in ohms. * A resistor has the resistance of one ohm if one volt is necessary to push a current of one amp through it. * Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire....
