In the circuit shown in the figure, the reading of the voltmeter is V 1 when only S 1 is closed, V 2 when only S 2 is closed and V 3 when both S 1 and S 2 are closed. From this we can conclude that

Options

  1. AV 3 > V 2 > V 1
  2. BV 2 > V 1 > V 3
  3. CV 3 > V 1 > V 2
  4. DV 1 > V 2 > V 3

Correct answer

B. V 2 > V 1 > V 3

Step-by-step solution

In series V ∝ R When S 1 is closed and S 2 is open V 1 = 3 E 4 When S 1 is open and S 2 is closed V 2 = 6 E 7 When S 1 and S 2 both are closed V 3 = 2 E 3
