Homework Statement
You are given a standard Wheatstone bridge, prove that the bridge is balanced if and only if [tex] R_x = R_3 \frac{R_2}{R_1} [/tex]. Subindexes depend on the names assigned to each resistance. Proving that if the bridge is balanced THEN the resistors satisfy said relationship is easy, I am having prouble proving that IF [tex] R_x = R_3 \frac{R_2}{R_1} [/tex] then the bridge is balanced.

I have been trying to prove this using Kirchoff's laws around as many paths as i could find, but I am getting nowhere.
