    Calculate the rms value of emf, given by \[E=50\sqrt{2}\,\,\sin \,\,\left( \omega t-\frac{\pi }{4} \right):\]

    A)  \[50V\]          

    B)  \[5V\]

    C)  \[2\sqrt{5}V\]           

    D)  None of these

    Correct Answer: A

    Solution :

    As, \[{{V}_{rms}}=\frac{{{V}_{0}}}{\sqrt{2}}=\frac{50\sqrt{2}}{\sqrt{2}}=50V.\]
