    A \[5\,\,cm\] long solenoid having \[10\,\,\Omega \] resistance and \[5\,\,mH\] inductance is joined to a \[10\,\,V\] battery. At steady state, the current through the solenoid  (in ampere) will be

    A) \[5\]                                     

    B) \[2\]

    C)  \[1\]                                    

    D)  \[zero\]

    Correct Answer: C

    Solution :

    At steady state, the current through the solenoid                 \[i=\frac{E}{R}=\frac{10}{10}=1\,\,A\]
