Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFCoefficient of coupling
The coefficient of coupling can be defined as a magnetic flux that is produced between two different coils while managing the flux successfully.
\(k={M\over \sqrt{L_1L_2}}\)
where, k = Coefficient of coupling
M = Mutual inductance
L1 and L2 = Self-inductance of two coils
Calculation
Given, L1 = 8H and L2 = 32H
k = 0.4
\(0.4={M\over \sqrt{8\times 32}}\)
M = 6.4 H
