     A coil of resistance R and inductance L is connected to a battery of emf E volts. The final current in the coil is

    A) \[\frac{E}{R}\]                                  

    B) \[\frac{E}{L}\]

    C) \[\sqrt{\left( \frac{E}{{{R}^{2}}+{{L}^{2}}} \right)}\]                         

    D) \[\sqrt{\left( \frac{EL}{{{R}^{2}}+{{L}^{2}}} \right)}\]

    Correct Answer: A

    Solution :

    Inductance plays no role for DC \[\therefore \]  Current in the coil \[(I)=\frac{E}{R}\]
