How the Length of a Wire Affects Its rampart In my physics coursework I am going to investigate the effect of the continuance of a outfit on its resistance. Resistance is the measure of how clear it is for circulating(prenominal) to hang up through a equip. period is the rate of flow of tear through a conductor, and it is thrifty in amps using an ammeter. To serve well me plan my investigating I have completed a preliminary sample in which I investigated the effect of the weightiness of a conducting outfit on its resistance, using three constantan conducting telegrams and one tinkers dam wire. I found that the resistance change magnitude as the thickness of the wire decreased, however, when I did the test with the copper wire I found that it was so unresistant that there would not be a lot of point in conducting my test using a copper wire beca practice session I would not really be able to comp ar the results. I therefore decided to use a wire of a higher r esistance; constantan, because it go out get me to get more than reliable and comparable results. Preliminary experiment results: Wire type/diameter         Resistance (W) Copper 0.2mm         1.8 W constantan 0.2mm         9.1 W Constantan 0.45mm         5 W Constantan 0.9mm         1.8 W Diagram: The things that I volition measure and find oneself are the voltage running through the wire and the current. This result allow me to calculate the resistance of the wire. To calculate the resistance of the wire I will divide the voltage (V) by the current (I), which will give me the resistance in ohms (W). Equipment: The equipment that I will use is: -         power pack -         ammeter -         voltmeter -         30 SWG (diameter) constantan wire -         1 metre ruler -         leads -         cr ocodile clips Method: This is on the gun! point what I will do: 1) ...
