Reciprocity Theorem, including what it is and its limitations

In this slide, you'll learn about the Reciprocity Theorem, including what it is and its limitations.

1. Description of Reciprocity Theorem

2. Reciprocity Theorem The Reciprocity Theorem states: If an ELECTROMOTIVE FORCE (E) in one branch of a reciprocal network produces a current (I) in another branch, then moving the electromotive force (E) from the first branch to the second will cause the same current in the first branch, where the original electromotive force has been replaced by a short circuit.

3. The location of the voltage source and the resulting current can be interchanged without changing the current. The theorem requires that the polarity of the voltage source maintains the same correspondence with the direction of the branch current in each position.

4. Limitations of Reciprocity Theorem: The limitation of this theorem is that it applies only to single-source networks, not multi-source networks. The network where the Reciprocity Theorem is used should be linear and consist of resistors, inductors, capacitors, and coupled circuits. Additionally, the circuit should not contain any time-varying elements.
