Directions: The question has 4 choices, out of which ONE OR MORE is correct.
For the circuit shown in the figure,
  • a)
    the current I through the battery is 7.5 mA
  • b)
    the potential difference across RL is 18 V
  • c)
    ratio of powers dissipated in R1 and R2 is 3
  • d)
    if R1 and R2 are interchanged, magnitude of the power dissipated in RL will decrease by a factor of 9
Correct answer is option 'A,D'. Can you explain this answer?

Rtotal = 2 +
(A) I = = 7.5 mA =
I = 1.5/7.5 × 7.5 = 1.5 mA
(D) When R1 and R2 are interchanged, then
Now, potential difference across RL will be:
Earlier, it was 9 V.
Since P = V2 / L
Or P ∝ V2
In new situation, potential difference has been decreased three times. Therefore, power dissipated will decrease by a factor of 9.
