# Inductance

### Explanation of question 2

The steady current through a 40mH inductor is doubled. The inductance will

1. decrease to 20mH
2. remain at 40mH
3. increase to 80mH
4. increase to 160mH

The answer is :- 2 The inductance of an inductor is fixed, and is not affected by a change in magnitude of current.
