STANDARD Physics Mutual Inductance MCQ Question
Type: MCQ-numerical-Medium-Class 12
Two coils of self-inductance 2 mH and 8 mH are placed so close together that the effective flux in one coil is completely linked with the other. The mutual inductance between these coils are
A
16 mH
B
10 mH
C
6 mH
D
4 mH
Correct Answer
Option D
Detailed Explanation
Mutual inductance between coils is calculated using M = K√(L₁L₂). Here, K = 1, L₁ = 2 mH, and L₂ = 8 mH. Therefore, M = √(2 × 8) = 4 mH.
