In a circuit, a voltmeter is used to measure the potential difference across a lamp. An ammeter is used to measure the current in the lamp. Which diagram shows the circuit?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
ACircuit diagram with ammeter in series with lamp and voltmeter in parallel with lamp, but voltmeter terminals connected incorrectly (positive to negative side of lamp).
BCircuit diagram with ammeter in series with lamp and voltmeter in parallel with lamp, with correct polarity.
CCircuit diagram with voltmeter in series with lamp and ammeter in parallel with lamp.
DCircuit diagram with ammeter and voltmeter both in series with lamp.
✓ Correct answer
B: Circuit diagram with ammeter in series with lamp and voltmeter in parallel with lamp, with correct polarity.
