effect of the length of a wire on resistance

Planning:
Aim:
To find out how the length of a piece of wire effects the reaction time in a circuit.
Background and general information:
In this course work investigation I will be trying to find out if the length of a piece of wire which is joined into a circuit effects the resistance. There is many reasons why the wire may cause more or less resistance. The length, temperature, thickness and the material the wire is made out of are all factors, which will effect resistance. I have decided to test how the length of the wire effects resistance as it is the easiest experiment to perform. Temperature and thickness of wire would be far too hard to set up and changing the type of material used each time for the wire would yield small results as we could only use maybe 5 or 6 different metals.
In my experiment I will only be recording the resistance from the different lengths. However the materials, temperature and thickness will still be very important, as they will still effect the resistance. I will try and keep the same wire each time simply making it shorter so it is the same material each time. AS it is the same wire the thickness won’t change either. The temperature of the wire should not change either, as I will be putting the same current in for each try.
