Question

In Circuit-1 and Circuit-2 shown in the figures, $R_1=1 \,\Omega, R_2=2 \,\Omega$ and $R_3=3\, \Omega P_1$ and $P_2$ are the power dissipations in Circuit-1 and Circuit-2 when the switches $S_1$ and $S_2$ are in open conditions, respectively $Q_1$ and $Q_2$ are the power dissipations in Circuit-1 and Circuit-2 when the switches $S_1$ and $S_2$ are in closed conditions, respectively. Which of the following statement(s) is(are) correct?|

• A. When a voltage source of $6 V$ is connected across A and B in both circuits, $P_1 < P_2$.
• B. When a constant current source of $2 Amp$ is connected across A and B in both circuits, $P_1>P_2$.
• C. When a voltage source of $6 V$ is connected across A and B in Circuit-1, $Q_1>P_1$.
• D. When a constant current source of $2 Amp$ is connected across A and B in both circuits, $Q_2 < Q_1$
