A digital simulation technique has been used to treat electrode reactions occurring at the rotating ring‐disk electrode (RRDE). The method of treating normal diffusion, normal and radial convection, and homogeneous kinetics at the RRDE is discussed and results for the transient and steady‐state currents at the disk and ring electrodes in the absence of kinetic complications are given. Where comparisons are possible, the simulated results were found to be in excellent agreement with previous theoretical treatments.
