Question

A pair of coils has mutual induction of 2H. If the current in the primary changes from
10A to 0 in 0.1 sec, the induced emf in the secondary will be ?​

Answer 1

I'm not from your friend list...

But I'm Online.....

When the current in a coil is changing an e.m.f will be induced in a nearby circuit due to some of the magnetic flux produced by the first circuit linking the second. ... M=-E di/dt Hence E= -Mdi/dt where E =emf, M= mutual inductance. E= -2 *(0-10)/0.1 =200 v .......
