Abstract The hysteric ring formed on sine waveform galvanodynamic polarization curve was investigated under the condition that the surface impedance may be represented by a polarization resistance R_p connected parallelly with a boundary capacitance C. Equations for polarization curve and the height of hysteric ring were derived and examined. It was found that R_p and C may be determined simultaneously from the height of hysteric ring. Because the height of hysteric ring was measured at i=0, the measurements were unaffected by solution resistance and thus this method may be used for high resistance system R_p and C of Fe in distilled water and in the tap water in Changchun were determined by the method proposed.
