    A 220 V, 50 Hz ac source is connected to an inductance of 0.2 H and a resistance of 20 ohm in series. What is the current in the circuit                                          [MNR 1998; JIPMER 2001, 02]

    A)            10 A                                         

    B)            5 A

    C)            33.3 A                                      

    D)            3.33 A

    Correct Answer: D

    Solution :

               \[i=\frac{220}{\sqrt{{{(20)}^{2}}+{{(2\times \pi \times 50\times 0.2)}^{2}}}}\]\[=\frac{220}{66}=3.33\,A\]
