Question

What does the Reciprocity Theorem of Mutual Inductance state?

विकल्प

• \[M_{12}=M_{21}=M\]

• \[M_{12}=0\] for every pair of coils

• \[M_{12}=L_1\] and \[M_{21}=L_2\]

• \[M_{12}=\frac{1}{M_{21}}\]

Answer 1

The mutual inductance of coil 1 with respect to coil 2 equals that of coil 2 with respect to coil 1. Thus, \[M_{12}=M_{21}=M\] .
