    The capacity of a condenser is \[4\times {{10}^{-6}}\]farad and its potential is 100 volts. The energy released on discharging it fully will be :

    A)  0.04 J                                   

    B)  0.02 J

    C)  0.025 J                                 

    D)  0.05 J

    Correct Answer: B

    Solution :

                    The energy released on discharging the capacitor fully, is given by \[E=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}\times 4\times {{10}^{-6}}\times {{(100)}^{2}}\] \[=2\times {{10}^{-2}}=0.02J\]
