Vedclass · Answer

(A) The relationship between magnetic flux $(\phi)$ and current $(I)$ for an inductor is given by $\phi = L I$,where $L$ is the self-inductance.From this,we can write $L = \frac{\phi}{I}$.In a graph of $\phi$ versus $I$,the slope of the line is given by $\frac{\phi}{I}$,which represents the self-inductance $L$.$A$ steeper slope indicates a larger value of $L$.Comparing the slopes of the lines $A, B, C,$ and $D$,line $A$ has the maximum slope.Therefore,inductor $A$ has the largest self-inductance.

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