    If an AC produces same heat as that produced by a steady current of 4 A, then peak value of current is:

    A)  4 A

    C)  5.6 A          

    D)  1.41 A

    Correct Answer: C

    Solution :

     The peak value of current \[({{I}_{0}})\]is given by \[{{I}_{0}}=\sqrt{2}\,{{I}_{rms}}\] where\[{{I}_{rms}}\]is known as root mean square value of current Given,      \[{{I}_{rms}}=4A\] \[\therefore \] \[{{I}_{0}}=\sqrt{2}\times 4=5.6A\]
