Abstract We recall briefly how the Ziman theory of electrical conductivity, first proposed for solids and liquid metals, has been extended to the case of plasmas. The physical assumptions and parameters entering the formula are analyzed. A self-consistent model of electronic and ionic structure of plasmas is then described and applied to the calculation of the resistivity. Results obtained for aluminum are shown and compared to measurements done by Benage, along a thermo-dynamic path going from normal density at melting to 0.03 compression at 41 eV. The important differences between theory and experiment are discussed. The uncertainties inherent to the theory are emphasized, and physical effects not taken into account in the theory are discussed. Finally, the need for accurate measurements is emphasized.
