摘要
In an electrochemical cell passing a constant current, an electrode rotating asymmetrically with respect to a fixed electrode produces an ac voltage, having a component at the rotational frequency, between the rotating and fixed electrodes because the interelectrode distance and dc solution resistance between the electrodes vary. When this electrode is used in an operating two electrode cell, e.g., a plating bath, the ac voltage may be used to map the spatial current distribution. Measurements of solution conductivity may also be made.
