Two coils have self-inductances of 10 H and 2 H, the mutual inductance being zero. If the two coils are connected in series, the total inductance will be_____________?
Correct answer: C. 12 H
- A. 6 H
- B. 8 H
- C. 12 H
- D. 24 H
Explanation
With zero mutual inductance, series inductances simply add: L = L₁ + L₂ = 10 + 2 = 12 H. Mutual coupling would introduce an additional term, but it is absent here.
