If R2 = RC RA / (RA +RB +RC ) then R3 equals?
(a) RA RB / (RA +RB +RC )
(b) RC RA / (RA +RB +RC )
(c) RB RC / (RA +RB +RC )
(d) RX RA / (RA +RB +RC )
This question was posed to me in unit test.
My question is taken from Measuring Resistance the Wheatstone Bridge and Delta-to-Wye (Pi-to-Tee) Equivalent Circuits topic in chapter Simple Resistive Circuits of Electric Circuits
