The Faradaic resistance of a redox couple O + ne (-) = R according to Butler-Volmer electrode kinetics is considered. The results of 1D theory are corrected for edge effects using the Oldham asymptote. The effect of convection at longer times is included using the recent model of a transient process for circular working electrodes in the LDC regime.
