Figure 3 shows a circuit used to determine the resistance per metre of wire X.
Figure 3
Two terminals are used to mount X on a ruler.
Clips are used to connect a voltmeter across the 1.2 Ω resistor.
When the switch is closed, the voltmeter reading is 931 mV.
The switch is then opened and the voltmeter is connected to X as shown in Figure 4.
