    In a circuit, the value of the alternating current is measured by hot wire ammeter as 10 ampere. Its peak value will be [MP PET 1996; AMU (Med.) 1999;  KCET (Engg./Med.) 2000; CPMT 2003]

    A)            10 A                                         

    B)            20 A

    C)            14.14 A                                   

    D)            7.07 A

    Correct Answer: C

    Solution :

               Hot wire ammeter reads rms value of current. Hence its peak value \[={{i}_{rms}}\times \sqrt{2}=14.14\ amp\]
