What is Reciprocal Property?In many electrical networks it is found that if the positions of voltage source and ammeter are interchanged, the reading of ammeter remains the same. It is not clear to you. Let’s explain it in details. Suppose a voltage source is connected to a passive network and an ammeter is connected to other part of the network to indicate the response.Now any one interchanges the positions of ammeter and voltage source that means he or she connects the voltage source at the pa
