Q. A $2\mu F$ capacitor is charged to $100\ volt$ and then its plates are connected by a conducting wire. The heat produced is
A) $1\ J$
B) $0.1\ J$
C) $0.01\ J$
D) $0.001\ J$
Explanation
(c) Heat produced = Energy of charged capacitor $= \frac{1}{2}CV^{2}$
$= \frac{1}{2} \times \left( 2 \times 10^{- 6} \right) \times (100)^{2} = 0.01J$
