Q. A 5.$\mu$F capacitor is charged to a potential difference of 800 V and discharged through a conductor. the energy given to the conductor during the discharge is
A) $1.6 \times 10^{- 2}\ J$
B) 3.2 J
C) 1.6 J
D) 4.2 J
Explanation
(c) Energy given to conductor $= \frac{1}{2}CV^{2}$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = \frac{1}{2} \times 5 \times 10^{- 6} \times (800)^{2}$
= 1.6 J
