Leanne Haines 11B Physics - Wires Investigation An investigation is being done to find out what affects the amount of resistance there is through a wire. Variables Input Outcome Length of Wire Resistance of wire Thickness of the wire (diameter / area) Resistance of wire Type of wire Resistance of wire The Temperature Resistance of wire To make the test fair, only one variable is going to be changed, the others will be left constant. The variable that I am going to change is the thickness of the wire. The type of wire I will be using is constantan. The length of the wire will be 90cm. The wire will be this length as the longer the wire, the less time it takes for it to heat up. If the wire becomes hot the results will change as the electrons in the wire gain more energy. The investigation will be done at room temperature and in the same room so that the temperature...
