1 A student wants to find the resistance of a piece of wire.
They clip the wire into a circuit with an ammeter, voltmeter and variable power supply.
The diagram shows how they clip the wire into the circuit.

(c) The student clips a new piece of the same wire in the circuit and repeats their method to find the
resistance.
The new piece of wire is double the length.
Describe how the resistance of the new length of wire is different to the resistance of the original
length of wire.
