How does the resistance of nichrome wire depend on its length?
Procedure:
In order to investigate how the resistance of nichrome wire depends on its length I will firstly have to know the formula for resistance (resistance = voltage ÷ current). So, in order to find the resistance of a length of nichrome wire, I need to put the wire in a circuit, and then measure the voltage across it and the current through it. I will do this for different lengths of nichrome, simultaneously recording my results.
