Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The mutual inductance is given by:
\(M = k{\sqrt{L_1L_2}}\)
where, M = Mutual inductance
L = Self-inductance
k = Coefficient of coupling
The value of k lies between 0 and 1.
The maximum value of mutual inductance is possible for k = 1.
Calculation:
Given, L1 = 10 mH
L2 = 40 mH
\(M = 1{\sqrt{10\space\times\space 40}}\)
M = 20 mH
