Question

The Reciprocity Theorem is applicable for __________

(a) Single-source networks

(b) Multi-source networks

(c) Both Single and Multi-source networks

(d) Neither Single nor Multi-source networks

I got this question during an internship interview.

This intriguing question originated from Advanced Problems on Reciprocity Theorem in section Useful Theorems in Circuit Analysis of Network Theory

Answer 1

The correct answer is (a) Single-source networks

Explanation: According to Reciprocity Theorem, the voltage source and the resulting current source may be interchanged without a change in current. Therefore the theorem is applicable only to single-source networks. It therefore cannot be employed in multi-source networks.
