Factors affecting the resistance of a wire Aim To find out if the length of the wire affects the resistance in it. Hypothesis I predict that the longer the wire is, the more resistance there will be. I think this, because in a longer wire, there are more chances of the atoms meeting than in a shorter piece of wire. Plan I will be investigating the amount of resistance in a constantan wire of the size 36. All the factors (type of wire) will stay the same; only the length will change. I will increase by 10.0cm each time until I reach 100.0cm. I am using the size 36 because I found out that this is a thin wire and the thinner the wire is, the more resistance there will be, meaning better results. There is a small resistance because current travels in straight lines and the closer the smaller the diameter of the...
