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
The mutual inductance between the coils is maximum when k = 1
Calculation
Given, L1 = 20H and L2 = 320H
k = 1
\(k={M\over \sqrt{20\times 320}}\)
M = 80 H
