What happens to the inductance of an inductor when its core becomes saturated?

  1. It rises sharply.
  2. It falls.
  3. It stays the same.
  4. It becomes capacitance.
Show answer

Correct answer: It falls.

A saturated core adds no more flux for more current, so there is no more opposing voltage.
