Vedclass · Answer

(A) The magnetic flux $\phi$ linked with an inductor is given by $\phi = LI$,where $L$ is the self-inductance of the inductor.Comparing this equation with the equation of a straight line $y = mx$,where $y = \phi$ and $x = I$,we get the slope $m = L$.Since the slope of the graph represents the self-inductance $L$,the inductor with the smallest slope will have the smallest value of self-inductance.Looking at the graph,the line $D$ makes the smallest angle with the current axis ($I$-axis),meaning it has the lowest slope.Therefore,inductor $D$ has the smallest self-inductance.

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