  • question_answer The peak value of A.C. voltage on a 220 volt mains will be:

    A)  \[240\,\sqrt{2}\] volt              

    B)  \[230\,\sqrt{2}\] volt

    C)  \[220\,\sqrt{2}\] volt       

    D)  zero

    Correct Answer: B

    Solution :

    RMS voltage \[{{V}_{rms}}=220\] volt. As we know that the rms voltage.                                                                         \[{{V}_{rms}}=220\,\,volt=\frac{Peak\,voltage}{\sqrt{2}}\] \[\Rightarrow \]               \[{{V}_{p}}=220\sqrt{2}\] volt.
