| Abstract: | A general theory is given on the electrical admittance of a parallel plate capacitor filled with a conductive medium containing charged particles by considering both their electric atmospheres and the electric field due to charges induced on the electrodes. The theory is applied to a dilute macroion solution with added salt and it is found that the low frequency dielectric response of the solution reflects the motions of the macroion and bound small ions and the effect of motion of the ion atmosphere around the macroion is canceled out by the current due to the induced charges on the electrodes. |
