Discussed are one-dimensional and two-dimensional cases of potential distribution in electrode. It is demonstrated that if the rate of current formation in each point of electrode was (according to Faraday's law-) proportional to transferred electrical charge as well as to deviation of potential from equilibrium potential, then the problem of potential determination brings to equation solution in the form: Δφ = k2φ , where Δ – Laplace operator; φ – potential deviation from equilibrium; k – a constant dependent on electrode parameters.
