An experiment to investigate the factors affecting the electrical resistance of a wire All wires in a circuit offer some resistance to the flow of charge. Wires with a low resistance allow electrons pass through easily, however, wires with a high resistance need more collision to move the electrons through them. By altering the resistance of a circuit, we are also changing the currents and voltages. Aim In this experiment, I am going to investigate how would the length affects the electrical resistance of a wire. Plan and fair-testing Circuit diagram of set up: Apparatus: 1. Voltmeter 2. Ammeter 3. Variable resistor 4. Battery 5. Wire 6. Wires for connections of the circuit 7. Crocodile clip By using the above circuit and the apparatus, I can then able to start my investigation. For this experiment, I am going to use 8 different lengths of wire and they will be from the range of 10 cm to 80...
