    In the circuit of given figure, the current following through resistance R at resonance is

    A)  zero                             

    B)  \[\operatorname{V}/R\]

    C)  \[\frac{\operatorname{V}}{\sqrt{{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}}}\]             

    D)  \[\frac{\operatorname{V}}{\sqrt{{{R}^{2}}+\,\,(1/\omega {{L}^{2}})}}\]

    Correct Answer: A

    Solution :

    At resonance, the currents through inductance and capacitance are equal in magnitude but opposite in phase. Hence, current through R will be zero.
