Effect of decreasing electrode size on the variation of the magnitude of the current density (A/m2) with depth along the radial line S, while maintaining the current density at point P constant. The electrodes were 18.8 cm apart (50% D). The legend gives the area (cm2) of the electrodes E1-E2, and the current intensity (mA).
