  • question_answer
    A capacitor of capacitance \[6\mu \,F\] is charged upto 100 volt. The energy stored in the capacitor is [BHU 2003; CPMT 2004; MP PMT 2005]

    A)            0.6 Joule

    B)                                      0.06 Joule

    C)                    0.03 Joule                       

    D)            0.3 Joule

    Correct Answer: C

    Solution :

               \[U=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}\times 6\times {{10}^{-6}}{{(100)}^{2}}=0.03J\]
