Answer:
Option B
Explanation:
according to question , peak value of current
l0=√2×lrms=2πA
Coefficient of mutual inductance =1H
as, we know induced emf in secondary coil is given by
Es=M.dldt [ where , l= l0 sinωt]
Es=M.ωl0cos(ωt)
= 1×2π×50×2πcos(2π×50×t)
(∴ω=2πn)
For t=0, we have
Ee = 4 x 50=200 V
