    A capacitor of capacitance of \[10\mu F\] is charged to 10 V. The energy stored in it is

    A)  \[100\mu J\]

    B)  \[500\mu J\]

    C)  \[1000\mu J\]

    D)  \[1\mu J\]

    Correct Answer: B

    Solution :

    : Here,  \[C=10\mu F=10\times {{10}^{-6}}F\] \[V=10V\] \[=\frac{1}{2}\times (10\times {{10}^{-6}}F){{(10)}^{2}}\]c \[=500\times {{10}^{-6}}J=500\mu J\]
