If the number of turns of coil increase, the inductance:
- Remains constant
- 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.
