Theory of multiple-cell response of redox electrodes

The theory is developed of the voltage of several cells connected in series that have an electrolyte bridge between each cell. The measured voltage increases as the ratio of the electrolyte resistance between cells to that within each cell is increased. Experiments with half cell compartments with platinum and silver electrodes in 0.001 mol dm^–3 potassium permanganate solution connected by thin tubes of different lengths showed a fit to theory if a small constant resistance was included.
