    An inductor and a capacitor are connected in an A.C. circuit inductance and  capacitance are 1 H and 25 \[\mu F\] then for maximum current, angular frequency will be (circuit is connected in series):

    A)  200 rad/sec       

    B)         50 rad/sec

    C)  100 rad/sec       

    D)         150 rad/sec

    Correct Answer: A

    Solution :

    For maximum current angular frequency. \[\omega =\frac{1}{\sqrt{LC}}\] \[=\frac{1}{\sqrt{1\times 25\times {{10}^{-6}}}}=\frac{1}{5\times {{10}^{-3}}}\] \[=200\,rad\,/\sec \]
