Abstract : The apparent or measured series resistance of an electrochemical cell is influenced by the geometry of the electrodes. At a dropping mercury electrode, the resistance increases as the frequency of the measuring signal decreases. The question arises as to how to correct for the series resistance when calculations are made of the faradaic impedance. It is shown here that the use of the high-frequency limit of the resistance gives better results than use of the apparent resistance at each frequency. Nevertheless, the correction made in this way represents only an approximation. (Author)
