If the number of turns of coil increase, the inductance will [Increase or Decreases] | Basic Electrical Engineering MCQ#18

by

If the number of turns of coil increase, the inductance:

  1. Decreases
  2. Increases
  3. Remains constant
  4. None of these

Correct answer: 2. Increases

Explanation of MCQ If the number of turns of coil increase, the inductance

If the number of turns of coil increases, the inductance will increases.

Let’s consider the air core coil inductor.

The inductor sizing equation of such coil is:

For the case given above and all other similar cases, the inductance is directly proportional to the number of turns of the coil and thus it increases as the number of coils is increased in the wire.
