Does Increasing the Length of a Copper Wire affect its Resistance? Prediction I predict that as the length of the wire increases I think that the resistance will increase as well. To show this I will need to do an experiment to calculate the resistance using the figures from the Ammeter and Voltmeter at all 10 lengths to see if it does increase. Current is the flow of electrons through a conductor. I will expect it to change in my experiment because as the current decreases the resistance will increase as well as there is more current needed to work against it if it moves in a longer piece of wire. Current is measured in Amperes or Amps (A or even I) Voltage is the electric pressure or the potential difference that pushes the electrons around the circuit I would expect it to change in my experiment because it increases due to the greater...
