Question 18

Multiple Choice

Capacitors in combination: In the circuit shown in the figure, the capacitors are initially uncharged. The switch is first thrown to position A and kept there for a long time. It is then thrown to position B. Let the charges on the capacitors be Q1, Q2, and Q3 and the potential differences across them be V1, V2, and V3. Which of the following conditions must be true with the switch in position B? Capacitors in combination: In the circuit shown in the figure, the capacitors are initially uncharged. The switch is first thrown to position A and kept there for a long time. It is then thrown to position B. Let the charges on the capacitors be Q<sub>1</sub>, Q<sub>2</sub>, and Q<sub>3</sub> and the potential differences across them be V<sub>1</sub>, V<sub>2</sub>, and V<sub>3</sub>. Which of the following conditions must be true with the switch in position B? A) V<sub>1</sub> = V<sub>2</sub> = V<sub>3</sub> B) V<sub>1</sub> + V<sub>2</sub> = V<sub>3</sub> C) V<sub>3</sub> = V<sub>0</sub> D) Q<sub>1</sub> = Q<sub>2</sub> = Q<sub>3</sub> E) Q<sub>1</sub> + Q<sub>2</sub> = Q<sub>3</sub>
