Techniques for the determination of ohmic drop in half-cells and full cells: A review

Abstract Different methods for the experimental determination of ohmic drop in batteries and half-cells are reviewed. The limitations in use of Luggin capillaries are defined. A novel method for elimination of ohmic error in high-resistance cells is described. This employs a programmable calculator or a minicomputer. By interpretation of the deviations from the log-rate law, values of internal resistance may be determined with some precision. A typical example is given and the results are compared with those obtained by classical oscillographic methods.
