Q. The heat generated through $2\ ohm$ and $8\ ohm$ resistances separately, when a condenser of $200\ \mu F$ capacity charged to $200\ V$ is discharged one by one, will be
A) $4\ J$ and $16\ J$ respectively
B) $16\ J$ and $4\ J$ respectively
C) $4\ J$ and $8\ J$ respectively
D) $4\ J$ and $4\ J$ respectively
Explanation
(d) Heat generated in both the cases will be same because the capacitor has the same energy initially
$= \frac{1}{2}CV^{2} = \frac{1}{2} \times 200 \times 10^{- 6} \times (200)^{2} = 4J$
