Aim: How does the resistance of Nichrome wire change as its length changes? Plan: First we connected the equipment as shown in the diagram above. The equipment that we will be using is as follows: Lengths of Nichrome wire: To pass the current through. Power Pack: To send the voltage through the Nichrome wire. Crocodile clips: To hold onto the Nichrome wire during the experiment. Voltmeter: To measure the voltage. Ammeter: To measure the current. Connecting wires: To connect the wire. Ice Pack: To keep the Nichrome wire cool during the experiment. Stop clock: To measure the time period. I have chosen to use Nichrome wire because from my preliminary results I found that this wire had the highest resistance, as copper burned up on the lowest voltage possible on the power pack and also in my preliminary test I found that the Nichrome wire would burn up you placed it up higher than 4 volts. This was the reason...
