Abstract
AbstractSinusoidal polarization of a single electrode has been shown in the literature to lead to a phenomenon called “faradaic rectification” or the “redoxokinetic effect”. This consists of a shift of the average potential away from its original value due to the sinusoidal polarization. This is reconsidered in this article by means of Lagrange's theorem. The results are in accordance with the more recent publications and resolve some of the discrepancies found in the older literature. It is also shown that the range of applicability of the final equation is greater than could be expected from the original derivation.
