Reciprocity Theorem

Reciprocity Theorem expresses that – In any part of a system or circuit, the current because of a solitary wellspring of voltage (V) in the system is equivalent to the current through that branch where the source was initially positioned when the source is again placed in the branch in which the current was initially gotten. This hypothesis is utilized in the respective straight system which comprises of reciprocal parts.

In straightforward words, we can express the correspondence hypothesis as when the spots of voltage and current source in any system are traded the sum or greatness of current and voltage streaming in the circuit continues as before. 

This hypothesis is utilized for explaining numerous DC and AC arrange which have numerous applications in electromagnetism gadgets. These circuits don't have whenever changing component. 

Clarification of Reciprocity Theorem 

The area of the voltage source and the current source might be exchanged without an adjustment in current. In any case, the extremity of the voltage source ought to be indistinguishable with the course of the branch current in each position. 

The Reciprocity Theorem is clarified with the assistance of the circuit chart demonstrated as follows.

The different protections R1, R2, R3 is associated in the circuit chart above with a voltage source (V) and a current source (I). It is obvious from the figure over that the voltage source and current sources are exchanged for understanding the system with the assistance of Reciprocity Theorem. 

The impediment of this hypothesis is that it is pertinent just to single-source systems and not in the multi-source organize. The system where correspondence hypothesis is applied ought to be direct and comprise of resistors, inductors, capacitors and coupled circuits. The circuit ought not have whenever differing components. 

Steps for Solving a Network Utilizing Reciprocity Theorem 

Stage 1 – Firstly, select the branches between which correspondence must be set up

Stage 2 – The current in the branch is gotten utilizing any regular system investigation technique. 

Stage 3 – The voltage source is traded between the branch which is chosen. 

Stage 4 – The current in the branch where the voltage source was existing before is determined. 

Stage 5 – Now, it is seen that the current acquired in the past association, i.e., in sync 2 and the current which is determined when the source is traded, i.e., in sync 4 are indistinguishable from one another. 

                                    This is about Reciprocity Theorem.
