    A \[50\text{ }mH\] coil carries a current of 2A, the energy stored in it (in joule) s

    A)  \[0.05\]                       

    B)  \[0.1\]

    C)  \[0.5\]                         

    D)  1

    Correct Answer: B

    Solution :

    Energy stored in an inductor is given by \[\varepsilon =\frac{1}{2}L{{i}^{2}}=\frac{1}{2}\times (50\times {{10}^{-3}})\,{{(2)}^{2}}=0.10\]
