The protection of a wire Aim: The resistance of a wire depends on certain factors. Investigate the effect of 2 of these factors Planning Some variables that will be relevant to this investigation argon: Length Thickness Temperature Voltage Resistance square Of these the variables will be input and output voltages in test one, and length and resistance in experiment two. The other variables (temperature, material and voltage) will have to be unbroken constant in both experiments to make sure that only length, thickness and resistance are investigated.
In experiment 1 the same catch of wire and the same thickness need to be kept constant. In experiment 2, the length will need to be kept constant to make sure only the variables indicated are investigated to ensure a fair test. Metals conduct electricity because the atoms in them do not hold on to their electrons very well, and so creating free electrons, carrying a negative charge to jump on the l...If you want to get a full essay, order it on our website:
