Experiment to discover how factors affect resistance in wire Aim To investigate how the length of wire affects its resistance. Hypothesis I predict that as the length of wire increases, the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage is the push which makes the electrons flow through the circuit. Resistance is caused by components in circuits which slow the flow of electrons down as it is harder for them to flow through the circuit. There is resistance in wire and as the electrons have further to travel through longer lengths of wire they face more resistance, therefore the longer a piece of wire is, the higher the resistance will be. The greater the resistance, the more voltage is needed to push a current through the wire. The resistance of a wire is calculated by the formula Resistance = Voltage/Current, which is known as...
