Electrical mathQuestion 897 of 1506

Two inductors of 40 mH and 60 mH are connected in parallel, with no mutual coupling. What is the total inductance?

  1. 100 mH
  2. 50 mH
  3. 24 mH
  4. 20 mH
Show answer

Correct answer: 24 mH

Parallel inductors follow the same form as parallel resistors: (40 × 60) / (40 + 60) = 24 mH.
