Abstract: To help the students have a better understand and usage of reciprocity theorem,in this paper,we propose a reciprocity theorem table. Based on the four forms of the ports at reciprocity theorem and the equivalent circuit of two port network with pure linear resistance,we study the reciprocity theorem. It has been shown the instinct property of the theorem is the equivalent response between the reciprocity circuit and the reciprocal circuit.

Key words: reciprocity theorem, instinct property of the reciprocity theorem, reciprocity theorem table, circuit analysis
