  • question_answer
    In an LCR circuit having L = 8 H, C = 0.5 \[\mu \]F and R = 100\[\Omega \] in series, the resonance frequency in rad/s is

    A)  600                                       

    B)  200

    C)  250/n                                  

    D)  500

    Correct Answer: D

    Solution :

                     From the formula \[\omega =\frac{1}{\sqrt{LC}}\] Given : \[L=8H,\]\[C=0.5\mu F=0.5\times {{10}^{-6}}F\] \[\therefore \]  \[\omega =\frac{1}{\sqrt{8\times 0.5\times {{10}^{-6}}}}\] \[\Rightarrow \]               \[\omega =\frac{1}{2\times {{10}^{-3}}}=500\,\text{rad/s}\]
