where L is the distance between the edge of the electrode and the side wall of the cell, and A is the electrode length. It was found experimentaly, using the bridge method, that Eq. (1) is valid up to k ≈ 1, when Reff ≈ 0.5Rh. The value ofReff does not change as k increases further. As a consequence of this, the current in a cell in which the edges of the electrodes do not touch the side wall will be considerably larger than in a cell in which the edges of the electrodes do touch the side walls (at the same cell voltage and inter-electrode distance and if the activation overpotential is not very large). It
