A plot of magnetic flux (phi) versus cur...

A plot of magnetic flux `(phi)` versus current (I) is shown for two inductors A and B. Which of the two has larger value of self inductance ?

Text Solution

Verified by Experts

Since ` phi= LI rArr L=(phi)/(I) =" slope of " phi -I ` graph `therefore` Slope of inductor `A= ` slope of inductor B. Hence, the inductor A has larger value of self inductance.
