A graph of magnetic flux ( ) versus current ( I ) is shown for four inductors P, Q R, S. The largest value of self-inductance is for inductor

Options

  1. AR
  2. BP
  3. CQ
  4. DS

Correct answer

B. P

Step-by-step solution

The magnetic flux through an inductor is directly proportional to the current I , with self-inductance L as the constant: = LI . Hence, L = I , which corresponds to the slope of the versus I graph. A steeper slope indicates greater self-inductance. From the graph, line P has the steepest slope, followed by Q, then R, and finally S with the least steep slope. Inductor P has the largest self-inductance.
