    The maximum value of a.c. voltage in a circuit is 707V. Its rms value is                                      [MP PET  2005]

    A)            70.7 V                                      

    B)            100 V                                       

    C)            500 V                                       

    D)            707 V

    Correct Answer: C

    Solution :

                       \[{{E}_{rms}}=\frac{{{E}_{0}}}{\sqrt{2}}=\frac{707}{1.41}=500V\]
