Two coils have a mutual inductance $0.55 H$ . The current changes in the first coil according to equation $I = I_{0} sin ω t$ . where, $I_{0} = 10 A$ and $ω = 100 π rad / s$ The maximum value of emf in the second coil is

Options:

Answer:

Solution:

$E.M.F. e = M \frac{di}{dt} = 0.005 \times \frac{d}{dt} (i_{0} sin ω t) = 0.005 \times i_{0} cos ω t e_{m a x} = 0.005 \times 10 \times 100 π = 5 π$
