Cedric Grimstead: A balance condition is when 2 arms of a bridge circuit have equal voltages/ currents/ impedances in each, so the difference between the arm centres = 0.Hard to know exactly what you are looking at!If you have 2 arms in a Wheatstone configuration which have R1 and R3 in 1 side in series, and R2 and R4 in the other, and R1 is 6 ohms, R2 is 2 ohms, R3 is 9 ohms,and R4 is 3 ohms, then (R1/R2) = 3, and (R3/R4) = 3, there is 0 voltage between the junctions of R1 & R3, and R2 & R4, when a voltage is applied between the junctions of R1 & R2, and R3 & R4. The bridge balances....Show more
