How Does the Shape of a Resistance Wire affect its resistance? I am going to see how the shape of a resistance wire affects its resistance. To do this, I will investigate how the length and thickness of the wire affects the resistance by doing two different experiments. Plan Equipment for both experiments: Power Supply Resistance wire (1m) Crocodile Clips 5 Wires Ammeter Voltmeter Diagram: Method for Experiment 1 (for investigating how the length of the resistance wire will affect its resistance): 1. Gather equipment and set up as in the diagram above. 2 Set the power supply to D.C. and 2 volts and switch on the power supply. 3. Read and record the ammeter and the voltmeter in the table. 4. Repeat steps 2 and 3, another four times, each time moving the crocodile clips so that 10cm more of the resistance wire is included in the circuit (i.e. the second time you do steps 2 and 3 there should be 20cm of...
