Reciprocity Theorem

qImage657de17b46a1f01616f85ca7

The reciprocity theorem states that in any linear and bilateral network or circuit having only one independent source, the ratio of response to excitation is constant even though the source is interchanged from the input terminals to the output terminals.

ExplanationF4 Savita ENG 28-12-23 D12

 

In both the above circuits, the source of excitation remains the same i.e. 100V. So the response will also be 10 A.

Hence, the correct answer is option 4.
