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,\[M=5\,\,H,\,\,di=10\,\,A,\,\,dt=0.5\,\,s\] \[\therefore \] \[e=-5\times \frac{10}{0.5}=-100\,\,V\] Note: Minus sign in the relation is reflection of Lenz's law.You need to login to perform this action.
