    In an ac circuit, peak value of voltage is 423 volts. Its effective voltage is                                                 [JIPMER 1997]

    A)            400 volts                                

    B)             323 volts

    C)            300 volts                                

    D)             340 volts

    Correct Answer: C

    Solution :

               Effective voltage \[{{V}_{r.m.s.}}=\frac{{{V}_{o}}}{\sqrt{2}}=\frac{423}{\sqrt{2}}=300\ V\]
