    Impedance of circuit when a resistance R and an inductor of inductance L are connected in series in an A. C. circuit of frequency v, is

    A) \[\sqrt{{{R}^{2}}+2{{\pi }^{2}}{{v}^{2}}{{L}^{2}}}\]

    B)        \[\sqrt{{{R}^{2}}+4{{\pi }^{2}}{{v}^{2}}{{L}^{2}}}\]

    C) \[\sqrt{R+4{{\pi }^{2}}{{v}^{2}}{{L}^{2}}}\]

    D)        \[\sqrt{R+2{{\pi }^{2}}{{v}^{2}}{{L}^{2}}}\]

    Correct Answer: B

    Solution :

    [b] Impedance\[=\sqrt{{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}}\] \[=\sqrt{{{R}^{2}}+4{{\pi }^{2}}{{v}^{2}}{{L}^{2}}}\]
