Which equation correctly represents the relationship between self-inductance (L), mutual inductance (M), and the number of turns (N 1 and N 2 ) for two closely coupled coils?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1M = L / (N 1 × N 2 )
- 2L = M / (N 1 + N 2 )
- 3L = M × N 1 × N 2
- 4M = L × √(N 1 × N 2 )✓
Correct answer
M = L × √(N 1 × N 2 )
