  • question_answer
    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 :

    The energy stored in a capacitor is \[U=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}\times \left( 10\times {{10}^{-6}} \right){{\left( 10 \right)}^{2}}=500\mu J\]
