A circuit is set up in order to determine the resistance of a 12 V, 1.2 W lamp when operating normally. An analogue ammeter and an analogue voltmeter are used. Which ranges for the meters would be most suitable?

1. Aammeter range 0–0.5 A, voltmeter range 0–20 V
2. Bammeter range 0–0.5 A, voltmeter range 0–100 V
3. Cammeter range 0–10 A, voltmeter range 0–20 V
4. Dammeter range 0–10 A, voltmeter range 0–100 V
