Physics investigation - Factors Affecting Resistance
Aim : T o find out how the varying length of a wire affects the amount of resistance
Method
* Get all equipment together that will be required; a power pack, a rheostat, voltmeter, ammeter, Constantium wire, leads and crocodile clips and check that all of these work correctly before setting up circuit as below
Variable length of wire
* Check that the circuit works correctly and that all wires are connected correctly, positive to negative and in correct places
