The noise resistance defined as the ratio of the standard deviations of the potential noise and the current noise has been empirically correlated to the polarization resistance in order to calculate the corrosion rate. The attitudes of investigators towards this correlation are still controversial because it is often said to lack theoretical background. Based on the principal electrochemical theory. a mathematical derivation of the noise resistance in electrochemical noise measurements is presented in this paper. It shows that the noise resistance is indeed equivalent to the polarization resistance.
