A graph of magnetic flux ( \(\phi\) ) versus current (I) is shown for four inductors A, B, C, D. Smaller value of self inductance is for inductor
- A D
- B C
- C B
- D A
Answer & Solution
Correct Answer
(A) D
Step-by-step Solution
Detailed explanation
From \(\phi=\) LI
Comparing the above equation with \(y=m x\), \(\mathrm{L}=\phi / \mathrm{I}\), which is the slope of the graph.
Since line D has lowest value of slope, it indicates the smallest value of self-inductance.
