ABSTRACT:
An electrochemical cell includes a metallic anode electrode and a metallic athode electrode substantially immersed in an electrolyte. As charge or current is passed through the cell from the anode electrode to the cathode electrode, the anode electrode is consumed and the cathode electrode plated, causing the resistance therebetween to change. The change in resistance provides a measure f or both the total charge passed through the cell over an interval of time, and for the total time charge flowed through the cell over an interval of time between resistance measurements.
