Reciprocity theorem is applicable to a network

1. Containing R, L and C elements

2. Which is initially not a relaxed system

3. Having both dependent and independent sources

Which of the above is/are correct?

Reciprocity theorem: It states that the current I in any branch of a network, due to single voltage source (E) anywhere in the network is equal to the current of the branch in which source was placed originally and when the source is again put in the branch in which current is obtained originally.

Limitations of reciprocity theorem:

• The network should be linear and time-invariant
• It can apply only to the single-source network
