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