Diagram 1 shows a voltmeter that is not connected to any circuit. It gives a small reading, known as a zero error, because it has not been set correctly. Diagram 2 shows the same meter being used to measure the p.d. across a resistor in a circuit. What is the p.d. across the resistor?
- A$4.6\ \text{V}$
- B$4.7\ \text{V}$
- C$5.2\ \text{V}$
- D$5.4\ \text{V}$
