    A \[2\,\mu F\]capacitor is fully charged by a 10 V battery and then it is discharged through a resistor. The heat dissipated in the circuit is

    A) \[\text{0}\text{.1J}\]                                     

    B) \[\text{ }\!\!~\!\!\text{ 0}\text{.01J}\]

    C)  \[\text{0}\text{.001J}\]

    D)  Information is insufficient

    Correct Answer: C

    Solution :

     Heat dissipated in the circuit is equal to energy stored in capacitor. \[\therefore \]  \[\Delta \Eta =\frac{C{{V}^{2}}}{2}=\frac{20\times {{10}^{-6}}\times 100}{2}=0.001\,J\]
