Question

Each of these is a method of changing the resistance of a wire except _____.Select one:a.changing the wire materialb.changing the cross-sectional areac.changing the voltage supplied to the circuitd.changing the temperature of the wiree.changing the length

Answer 1

Changing the voltage supplied to the circuit will not change the resistance of the wire. The resistance of a wire is independent of the voltage.

Therefore, the answer is c
