    The peak value of AC voltage on a 220V mains is:

    A)  \[240\sqrt{2}V\]        

    B)  \[230\sqrt{2}V\]

    C)  \[220\sqrt{2}V\]        

    D)  \[200\sqrt{2}V\]

    Correct Answer: C

    Solution :

     Here: rms voltage\[{{V}_{rms}}=220\,V\] Using the relation, \[{{V}_{rms}}=\frac{peak\text{ }voltage}{\sqrt{2}}\] Hence, peak value of A.C. voltage \[{{V}_{P}}=220\sqrt{2}V\]
