Siobhan Higgins G.C.S.E Science Coursework AT1 Aim- The aim of our investigation is to investigate Ohms Law. Introduction- In my investigation I am trying to prove that Ohm's law works. Ohm's law is used to find a value in a missing circuit. Georg Ohm, a German physicist proved that resistance is equal to voltage divided by current. Resistance is the difficulty in getting the current round the circuit. I will test the resistance of different lengths of nichrome wire. Prediction and Hypothesis I predict that the wider apart the crocodile clips are, the higher the resistance is. I know this as the longer the wire, the more free electrons there are, which means more collisions, which results in higher heat loss. Method- To make the test fair I need to repeat the test five times, and make sure I get accurate results. I will have to make sure that the crocodile clips are placed...
