    A coil of 100 turns carries a current of 5 mA and creates a magnetic flux of 10?5 weber. the inductance is [Orissa JEE 2002]

    A)            0.2 mH                                    

    B)            2.0 mH

    C)            0.02 mH                                  

    D)            None of these

    Correct Answer: B

    Solution :

               \[{{\varphi }_{T}}=Li\Rightarrow L=\frac{{{10}^{-5}}}{5\times {{10}^{-3}}}=2mH\]
