Current Distributions on Recessed Electrodes
The primary current distributions on disk electrodes and two-dimensional electrodes that are recessed in insulating planes are given. The ohmic resistances are also given and are compared to previous estimates that were given in Ref. (2-5). A singular-perturbation analysis, valid for small aspect ratios, shows general behavior to be expected for all cells containing an electrode that is recessed slightly from the insulating plane
