  • question_answer
    A resonant ac circuit contains a capacitor of capacitance \[{{10}^{-6}}F\] and an inductor of \[{{10}^{-4}}H.\] The frequency of electrical oscillations will be

    A)            \[{{10}^{5}}\,Hz\]               

    B)            10 Hz

    C)            \[\frac{{{10}^{5}}}{2\pi }Hz\]

    D)            \[\frac{10}{2\pi }Hz\]

    Correct Answer: C

    Solution :

               \[\nu =\frac{1}{2\pi \sqrt{LC}}=\frac{1}{2\pi \sqrt{{{10}^{-6}}\times {{10}^{-4}}}}=\frac{{{10}^{5}}}{2\pi }Hz\]
