Abstract
Abstract This work reports an analytical method for determining electrical resistivity ( ρ ) and sheet resistance ( R S ) of isotropic conductors. The method is compared with previous numerical solutions and available experimental data showing a universal behavior for isotropic conductors. An approximated solution is also reported allowing one to easily determine ρ and R S for samples either with regular or arbitrary shapes.
