Mutual Inductance from Flux LinkageHardQuestion 20239

Question

When current 4 A flows in coil 1, the flux linkage (NΦ) in coil 2 is 0.08 Wb-turns. Mutual inductance M is:
  1. A
    0.02 H
    Correct
  2. B
    0.2 H
  3. C
    0.32 H
  4. D
    0.008 H

Correct answer

0.02 H

Explanation

M = NΦ/I₁ = 0.08/4 = 0.02 H.
