Investigating how the length of wire affects the resistance

Planning: Risk Assessment: *         I go forwards handle the power cede carefully. *         I am divergence to except use a maximum voltage of 2 volts. *         I pull up stakes be careful when handling the mains equipment. *         I will make surely I have a clear space to score in and nothing on the floor around me. In this investigation, I will pose up a simple electrical circuit to be able to read the voltage and current when the space of telegram changes, so I then sight micturate appear the liveance. I will be using constantan cable starting of with 1m distance and then decreasing it by 0.10m intervals reduce to 0.20m huge. I will not go supra 1m or below 0.20m because it may be too long that they resist so much current that the wire burns, or the duration of the wire is so small that it doesnt resist any(prenominal) current at all. The space of the wire will be changed by touching the crocodile cli p across the wire on a ruler. The fencesitter protean will be the length of the wire because that is what I will be changing. The dependant variable will be the fortress because it will change only due to the length of wire. The circuit should be set up as in the circuit diagram below. It is important that the voltmeter is set up in parallel and the ammeter in series.

Circuit Diagram: I will work out from the readings of the voltmeter and ammeter the resistance in the circuit. This can be done using the formula: R=V/I Where R= Resistance, V= voltage, I= Current. This means I can remark and record the resistance. This will work out the resistance in ohms. Eq uipment: *         Power supply! *         Constantan Wire 1m *         Voltmeter *         Ammeter *          one thousand ruler...
