Investigation on Resistance of Wires
resistance is inversely proportional to 1 thickness2). I think this because there are more collisions between the electrons and atoms in a longer wire there fore since the electrons carry the charge therefore less current will get through. Take an average of the 3 tests to ensure accuracy. Next, change the thickness of the wire and do the experiment again. I need to do this so that I can test the safety of my experiment, the accuracy of the experiment and to confirm what variables to use.
Record the results from the ammeter n voltmeter. Coursework : Resistance of Wire - StudyMode, physics, gCSE coursework : Resistance of wire Aim: To investigate if the length of wire affects its resistance. Take four readings like this so that an average resistance can be found. Analysis of Results: From the graph and table of results i can see a pattern emerging. This includes resistivity, (Resistivity (R A l, Where R is the resistance of the conductor, A is the cross-section in square metres, l is the length of the conductor.). To ensure accuracy make sure I redid the tests three times. If there are twice as many electrons getting through, as there is twice the current, the resistance must have halved.
