  • question_answer
    In an inductor of inductance L = 100 mH, a current of \[I=10A\] is flowing. The energy stored in the inductor is [Orissa PMT 2004]

    A)            5 J  

    B)            10 J

    C)            100 J                                        

    D)            1000 J

    Correct Answer: A

    Solution :

               \[U=\frac{1}{2}L{{i}^{2}}=\frac{1}{2}\times 100\times {{10}^{-3}}\times {{(10)}^{2}}=5J\]
