✦ Synopsis

In the present paper some boundary value problems are examined, concerning diffusion toward a planar, a spherical, or a dropping electrode, held at constant potential. In so doing, it will be shown with practical examples that the direct application both of the unified numerical procedure and of the approximate procedures described in Part I* leads easily to i-E characteristics as well as to potentiostatic i t curves. The satisfactory degree of accuracy of the approximate methods will be apparent from the direct comparison between the results obtained by these methods and those obtained by the rigorous numerical procedure.
