Conclusion

My hypothesis was correct. The nichrome wire has a higher resistance than the copper wire and the longer the wire, the higher the resistance.

Ohm's law states that the current flowing through the circuit is directly proportional to the voltage applied. (If you double one, you double the other.)

I worked out the resistance of the wires by using the formula:
V/I = R or v = I x R
