Question 15

Electromagnetic Induction

If two inductors of inductances 3H and 6H are arranged in series, the total inductance is

  1. A.18.0 H.
  2. B.9.0 H.
  3. C.2.0 H
  4. D.0.5 H
Show the answer and explanation

Answer: B (9.0 H.)

Explanation

Inductors in series add (like resistors): 3 + 6 = 9 H.
