Reciprocity theorem

In a linear, bilateral network, the ratio between response the excitation remains the same even after the position of response and excitation are interchanged.

F2 Vinanti Engineering 09.01.23 D6 F2 Vinanti Engineering 09.01.23 D7

In fig (a) and (b), the position of excitation (E) and response (I1) are interchanged, but according to the reciprocity theorem, the ratio of response and excitation will remain unchanged.

Limitations of the reciprocity theorem

  • It is applicable only to single-source networks and not to multisource networks.
  • It is not applicable to circuits consisting of any time-varying element.
  • It is not applicable to the circuits consisting of the dependent source even if it is linear.
  • It is not applicable to circuits consisting of non-linear elements like diodes, transistors, etc.
