OBJECTIVE
For this piece of coursework I have been asked to investigate into the resistance of wires when the length is changed.
INTRODUCTION
The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance.
There are factors which can affect how accurate our expriment is come on four levels.
As in any scientific experiment, there are always variables ( "likely to change or vary subject …

…to the results. Crocodile clips have their own resistance but were vital to connect the components together, next time, or in a repeat of the test I would not use the clips, I would connect the wires without using Crocodile clips.
To prove my theory even more so i would double the length of the wire, two to three times more untill 300cms, the resistance should still be proportaional to the length of the wire.
