Resistance Investigation

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.
Method:
1. Collect all equipment needed for experiment.
2. Set up circuit.
3. Measure out the different lengths of wire.
4. Carry out exper…
