I will connect the first wire, then run the pre determined voltage through it, waiting a short time until the ammeter has rested upon one result, and then record that result. I shall take 7 readings, each following the same procedure as the first, each of which will be of a different wire diameter. I will be using the following 7 wire sizes: To ensure that these are in fact the correct diameters, as part of my pre-test, I shall use a micrometer to accurately read their diameters in 3 different places, and therefore work out an average thickness...

I will be using the following 7 wire sizes: To ensure that these are in fact the correct diameters, as part of my pre-test, I shall use a micrometer to accurately read their diameters in 3 different places, and therefore work out an average thickness. If time permits I will perform more tests on each wire, so I can work out an average, and possibly discount anomalous results...

Resistance of a wire The points are very close to the line of best fit or even touching it. This showed that the results were directly proportional throughout the experiment, as the line does not curve suddenly or curve or bend at all in any way, as the gradient of the line stayed the same throughout...	2 / 316

Resistance of a Wire I'll do six different readings, varying the length in each reading. ? Dependent variable ? what you'll measure. I'll measure the resistance in each reading...	3 / 755
factors affecting wire As the length goes up the resistance goes up. I predict this because the moving electrons in the wire will have to travel twice as much when moving up the wire...	3 / 603
