Abstract
An 'exact' numerical solution of Laplace's equation is performed in or der to extract the anisotropic resistivity in a single crystal of a su perconducting oxide from a multi-terminal transport measurement. A phe nomenological fit of the results is proposed to provide a very simple method of extraction of the anisotropic resistivity. This extraction i s successfully applied in a crystal of (Tl, Bi)Sr2CaCu2O7 at room temp erature.
