Questions
Two coils have their mutual inductance 0.005 H. The current changes in the first coil according to equation i = 10 sin 100t A. The maximum value of emf in the second coil in volt, is
detailed solution
Correct option is B
didt=1000πcos100πt A/s⇒didtmax=1000π A/s∴ εmax=Ldidtmax=5×10-3×1000π volt=5π volt.Talk to our academic expert!
