Question

A $2\mu F$ capacitor is charged to $100V$ and then its plates are connected by a conducting wire, the heat produced is :

• A. $1J$
• B. $0.1J$
• C. $0.01J$
• D. $0.001J$

Answer 1

Answer: (C)

$0.01J$

Here $C=2\mu F$, $V=100$ volt

Heat produced $H=\frac{1}{2}C{V}^2$

$=\frac{1}{2}(2\times {10}^{-6})\times {\left(100\right)}^2$

$=1\times {10}^{-2}J$

$=0.01J$
