    An LC circuit is in the state of resonance. If \[C=0.1\mu F\]and \[L=0.25\] H, neglecting ohmic resistance of circuit, what is the frequency of oscillations?

    A) 1007 Hz                                

    B) 100 Hz

    C) 109 Hz                                  

    D) 500 Hz

    Correct Answer: A

    Solution :

    From the formula, the frequency of oscillation is \[f=\frac{1}{2\pi \sqrt{LC}}\] \[=\frac{1}{2\pi \sqrt{0.25\times 0.1\times {{10}^{-6}}}}\] \[\approx 1007\,Hz\]
