Electromagnetic Induction

Question:

The self inductance of an inductor does not depend on the:

Options:

number of turns per unit length

permeability of the medium inside the inductor

area of cross-section of the inductor

current flowing through the inductor

Correct Answer:

current flowing through the inductor

Explanation:

The correct answer is Option (4) → current flowing through the inductor

The self-inductance (L) of an inductor is determined by -

$L=\frac{μN^2A}{l}$

It does not depend on the current flowing through the inductor, as self inductance is a property of the inductor itself, not a current passing through it.
