    An oscillator circuit consists of an inductance of 0.5mH and a capacitor of 20\[\mu F\]. The resonant frequency of the circuit is nearly                                                         [Kerala PET 2002]

    A)            15.92 Hz                                 

    B)            159.2 Hz

    C)            1592 Hz                                   

    D)            15910 Hz

    Correct Answer: C

    Solution :

               \[{{\nu }_{0}}=\frac{1}{2\pi \sqrt{LC}}=\frac{1}{2\times 3.14\sqrt{5\times {{10}^{-4}}\times 20\times {{10}^{-6}}}}\] \[{{\nu }_{0}}=\frac{{{10}^{4}}}{6.28}=1592\,Hz\]
