What Factors affect the resistance of a piece of wire(evaluation missing)

Aim: The aim of this is to investigate how the length of a wire affects the resistance of it. Prediction: I predict that the longer the piece of wire, the greater the resistance will be. This is due to the idea of the free moving electrons being resisted by the atoms in the wire. In a longer piece of wire, there would be more atoms for the electrons to collide with and so the resistance …showed first 75 words of 915 total…

…showed last 75 words of 915 total…in the prediction I said that as the wire length increased, the resistance should increase. I also said that the link should be directly proportional. The results have shown that this is true. The line of best fit clearly show that the results followed the expected pattern very well. The points are very close if not touching the line. This shows how the results were directly proportional through out, as the gradient remained the same.
