Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFCoefficient of coupling
The coupling coefficient can be defined as a magnetic flux 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
Explanation
The value of k lies between 0 and 1. The maximum value of k = 1.
\(1={M\over \sqrt{L_1L_2}}\)
\(M=\sqrt{\mathrm{L}_1 \times \mathrm{L}_2}\)
