A graph of magnetic flux $(\phi)$ versus current (I) is shown for 4 different inductors $P, Q, R, S$. Minimum value of inductance is for inductor
P
Q
R
S
Solution
Flux, $\phi=$ LI
Comparing the above equation with $\mathrm{y}=\mathrm{mx}$, $\mathrm{L}=\phi / \mathrm{I}$, which is the slope of the graph.
Since line S has least slope, it indicates the smallest value of self-inductance.
