    The resonant frequency of an LCR circuit occurs at a frequency equal to:

    A)  \[\frac{1}{LC}\]                               

    B)  \[\frac{1}{\sqrt{LC}}\]  

    C)         \[\frac{1}{LCR}\]             

    D)         \[\frac{1}{CR}\]

    E)  \[\frac{1}{\sqrt{LCR}}\]

    Correct Answer: B

    Solution :

    At resonance con \[{{\omega }_{0}}L=\frac{1}{{{\omega }_{0}}C}\] \[{{\omega }_{0}}=\frac{1}{\sqrt{LC}}\]
