  • question_answer
    The rms value of current in an AC circuit is 25 A, then peak current is:

    A) 35.36 mA                     

    B) 35.36 A

    C) 3.536 A                        

    D) 49.38 A

    Correct Answer: B

    Solution :

    (b) 35.36 A Here,                 \[{{l}_{rms}}=25\,A\] \[\therefore {{l}_{m}}=\sqrt{2}\,{{l}_{rms}}=\sqrt{2}\times 25=35.36\,\,A\]
