The Laplace equation for the electrical potential was solved for a cylindrical domain that contains a concentric nonconductive obstruction. As the central obstruction radius approaches zero, an equation for electrical potential in an homogeneous domain is obtained, leading to an expression for the effective conductivity. %8 2000-12-01
