... and then turn the power supply off again so the wires do not overheat, then add my readings to my result table. The first wire I will experiment on will be Constantan wire with a SWG of 28. I must then induce the wire with two voltages of 2v and 3v. For every voltage I must take down different readings and make sure the power supply is switched off every time after I have noted down my results from the ammeter and voltmeter. Trial 2: After I have finished inducing the voltages, I must then disconnect all of my apparatus, so that I can begin the experiment with the next SWG wire, which will be Manganin. Then I will repeat the experiment again inducing the same voltages then add my readings to my results table. Trial 3: The next wire I will test will be Copper, but before I do that must ...
