A) 1 V
B) 10 V
C) 5 V
D) 100 V
Correct Answer: D
Solution :
From Faraday?s law of electromagnetic induction, the induced emf [e] is given by \[e=-M\frac{di}{dt}\] Given, \[M=5H,di=10A,dt=0.5s\] \[\therefore \] \[e=-5\times \frac{10}{0.5}=-100\,V\] Note: Minus sign in the relation is reflection of Lenz's law.You need to login to perform this action.
