The paper theoretically examines parallel electrode processes occurring under conditions when the product of one of them is involved in a homogeneous reaction with a reactant of the other. As a result the limiting current of the second reaction depends on the current of the first, and an effect is seen which was called a "latent limiting current" by Kemula and Grabowski. The analytical and numerical calculations performed cover a wide range of parameters of the problem, and include the results of Kemula and Grabowski as a particular case for the limit of an infinitely high rate constant of the homogeneous reaction.
