Hypothesis: Does the Diameter of the wire affect the Resistance?

I am going to investigate what factors affect the resistance of a wire. There are three main factors which affect the resistance of a wire: The material of the wire. (What the wire is made out of) The length of the wire. The thickness of the wire. (The diameter of the wire) Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the …

…used was fine, although it was extremely hard to collect any results for copper wire. This is because copper has such low resistance. It has a low resistance there will be a large current. The ammeters we have in school cannot read such a high current. Without the current I cannot work out the resistance of the wire. I ended up using some results I had already collected the last time I did this experiment.
