A) 8H
B) 4H
C) 3H
D) 2H
Correct Answer: D
Solution :
Coefficient of mutual induction of two coils is equal to the number of magnetic flux \[E=-\frac{E}{2}\] linkages in one coil when a unit current (i) flows in the other. Therefore, \[3.9\Omega \] Given, \[\therefore \] \[V=E-ir\] \[i=\frac{E}{R+r}\]You need to login to perform this action.
