Practical circuits — practice question

An electric circuit has been arranged to find the resistance of a $12\ \text{V}$, $1.2\ \text{W}$ lamp while it is working normally. An analogue ammeter and an analogue voltmeter are employed. Which meter ranges would be the most appropriate?

  • Aammeter range $0$-$0.5\ \text{A}$, voltmeter range $0$-$20\ \text{V}$
  • Bammeter range $0$-$0.5\ \text{A}$, voltmeter range $0$-$100\ \text{V}$
  • Cammeter range $0$-$10\ \text{A}$, voltmeter range $0$-$20\ \text{V}$
  • Dammeter range $0$-$10\ \text{A}$, voltmeter range $0$-$100\ \text{V}$
