What I am going to investigate is how the diameter of a wire affects the resistance of the wire.
I plan to change the diameter of the wire.
In order to keep it a fair test I will need to keep the following things the same:
-The same voltage of electricity entering the circuit (I used 6V)
-The length of the wire
-The temperature
-The type of wire
I have identified …

…the circuit and the ammeter and voltmeter will start reading the current and volts. You will record these readings, and turn off the power pak. The same steps will be applied for the following lengths: 30cm, 40cm, 50cm, 60cm, 70cm, 80cm.90cm and 100cm. To make it a fair test each test will be repeated three times. After you have collected all the data you will calculate the resistance using ohm's law (R=V/I).
