Hence we observe that when the sources was in branch x-y as in figure 1, the a-b branch current is 1.43A; again when the source is in branch a-b (figure 2), the x-y branch current becomes 1.43A. This proves the reciprocity theorem.

History of the reciprocal theorem in continuum mechanics, electricity, magnetism and optics The reciprocal theorem has been attributed to various famous ﬁgures in different ﬁelds of physics and engineering (see ﬁgure1b), though there is hardly a consensus on who was the founder.

The second term in the equation would trivially be zero, since d y = 0, and we'd get the trivial result: ( ∂ f ∂ x) y = ( ∂ f ∂ x) y. A more interesting result appears if we carefully divide Equation ( 1) by d f, but we still keep y constant.
