For the circuit shown in the figure
- the current I through the battery is 7.5 mA
- the potential difference across RL is 18 V
- ratio of powers dissipated in R1 and R2 is 3
- if R1 and R2 are interchanged, magnitude of the power dissipated in RL will decrease by a factor
of 9.
Answer
(D) if R 1 and R 2 are interchanged, magnitude of the power dissipated in R L will decrease by a factor of 9.
