Aim: The aim of the investigation is to find out whether or not the length of the wire affects the resistance.
Prediction: I predict that as the wire increases in length the resistance will increase, (collision of particles causing a decrease in velocity for the moving particle). I think this will happen because as the resistance increases the ions are closer together causing more collisions slowing down the velocity of the current through the wire.
1. Collect all equipment needed for experiment.
2. Set up circuit.
3. Measure out the different lengths of wire.
4. Carry out exper…
