Q. A 10 $\mu F$ capacitor is charges to 500 V and its plates are joined together through a resistance of 10 $\Omega.$ The heat produced in the resistance is
A) 500 J
B) 125 J
C) 250 J
D) 1.25 J
Explanation
(d) Heat produced =energy stored in capacitor
$\frac{1}{2}CV^{2} = \frac{1}{2}\left( 10 \times 10^{- 6} \right)(500)^{2}$
$= 1.25$ J
