Q.2. A graph of magnetic flux (ϕ) versus current (I) is plotted for four inductors A, B, C, D. Larger value of self inductance is for inductor
A. A
B. B
C. C
D. D
Answer :- A.
Explanation :-
From ϕ=LI
Comparing the above equation with y=mx, L=ϕ/I, which is the slope of the graph.
Since line A has highest slope, it indicates the largest value of self-inductance.
