A bstract A mathematical expression for potential of a direct current point source in an inhomoge‐neous anisotropic earth is derived. The coefficient of anisotropy is given by f = (σ r /σ z ), where σ r and σ z are the conductivities parallel and perpendicular to the bedding plane. It is assumed that σ z varies with depth, whereas σ r varies transversely. This potential may be useful in interpretation of geoelectrical data in specified geological situations. Master curves for Wenner and Schlumberger configurations are presented
