In Circuit-1 and Circuit-2 shown in the figures, and and are the power dissipations in Circuit-1 and Circuit-2 when the switches and are in open conditions, respectively. and are the power dissipations in Circuit-1 and Circuit-2 when the switches and are in closed conditions, respectively. Which of the following statement(s) is(are) correct?

Options:(select one or more)

Answer:
A, B, C
Solution:

With switches open, and . For a voltage source , so - (A) correct; for a current source , so - (B) correct.

With switches closed, , so for a voltage source - (C) correct. Since , a current source gives , so (D) is wrong.
