A graph of magnetic flux $(\phi)$ versus current $(I)$ is drawn for four inductors A,B,C, D. Larger value of self-inductance is for inductor

Correct answer
A
A
B
D
C
C
D
B

Solution

We have $\phi=L I$ or $L=\frac{\phi}{l}$ Self-inductance is given by the slope of the graph; slope of line A has the maximum value and therefore, largest self-inductance.

Hence, the correct answer is option: 'A'.
