## Description

**Problem 1. **Consider an air-core inductor with an inductance of 5.6 mH.

- a) Calculate the new inductance if we increase the number of turns by a factor of 3.
- b) Calculate the new inductance if the length of the inductor is increased by a factor of 3.

**Problem 2. **Calculate the rate of change of flux linking in a coil when 20 V are inducted across a 200-turn coil.

**Problem 3. **Calculate the voltage inducted across a 22 mH coil if the rate of the change of the current is 1 mA/ms. Repeat the problem for a rate of change of 2 mA/10 µs.
