Reciprocity theorem states that ______.

Reciprocity theorem states that ______.
A. Ratio of current in one mesh to voltage in second mesh must be similar.
B. Ratio of voltage in one mesh to current in second mesh must be similar
C. Ratio of current in one mesh to voltage in same mesh are nearly similar
D. Ratio of voltage in one mesh to current in same mesh are almost similar

a. A & B
b. only C
c. B & D
d. C & D

Correct Answer : a. A & B

Explanation :

Reciprocity is consigned for the reciprocal or interchanged ratios of voltage & current but in different nodes. However, both statements (A & B) are correct to maximum extent since the criteria of similar mesh interchangeable ratios are highly impossible for any kind of RLC network.
