which of the following can produce maximum induced
voltage..... (a)1amp dc current (b)50amp dc current (c)
1amp 60 cycle ac current (d)1amp 490 cycle ac current.
Answer Posted / nithi
1 amp 490 cycle ac current.
Reason: changing speed (frequency) of current is fast as
it completes 490 cycles per second (i.e. di/dt).so the
induced emf (L di/dt) is maximum compared to the other
cases given.
