page 09 15. A circuit is set up as shown. V 10 Ω 10 Ω 10 Ω S A1 A2 12 V The battery has negligible internal resistance. A student makes the following statements about the readings on the meters in this circuit. I When switch S is open the reading on the voltmeter will be 6·0 V. II When switch S is open the reading on A2 will be 0·60 A. III When switch S is closed the reading on A1 will be 0·80 A. Which of these statements is/are correct? A I only B II only C I and II only D II and III only E I, II and III 16. The power dissipated in a 120 Ω resistor is 4·8 W. The current in the resistor is A 0·020 A B 0·040 A C 0·20 A D 5·0 A E 25 A.
