2020-2-5 · Seeing the current is the same through each resistive load, we can multiply each term by the current (I) and the equation becomes V T = V V + V B or V V = -V B + V T. We also know that the resistance of 2 salt bridges is half that of 1 salt bridge, so the resistance of "n" salt bridges is R B x 1/n. We thus end up with an equation: V V = -V B x
