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

As `phi = LI , L = (phi)/(I) =` slope of `phi - 1` graph.
Since slope of `phi-I` graph for inductor A is greater than slope of `phi-I` graph for inductor B, therefore, inductor A has larger value of self inductance than B.
