  • question_answer
    An ac voltage is applied to a resistance R and an inductor L in series. If R and the inductive reactance are both equal to \[3\,\Omega \], the phase difference between the applied voltage and the current in the circuit is

    A) \[\pi /6\]  

    B) \[\pi /4\]  

    C) \[\pi /2\]  

    D) zero

    Correct Answer: B

    Solution :

    [b] The phase difference\[\phi \]is given by \[\tan \,\phi =\frac{{{X}_{L}}}{R}=\frac{3}{3}=1\Rightarrow \phi =\frac{\pi }{4}\]
