Question

For the Reciprocity Theorem to satisfy the ratio of response to excitation before and after the source is replaced should be?

(a) different

(b) same

(c) before source is replaced is greater than after the source is replaced

(d) before source is replaced is less than after the source is replaced

The question was posed to me in an internship interview.

My enquiry is from Reciprocity Theorem in section Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct choice is (b) same

Easiest explanation: For the Reciprocity Theorem to satisfy the ratio of response to excitation before and after the source is replaced should be same and if that condition satisfies the reciprocity theorem is valid for the given circuit.
