Abstract: The static conductivity of a system of Coulomb particles with strong interaction of ions at arbitrary degeneracy of electrons is investigated. To study the influence of structure on static conductivity, the pair correlation function and structure factors are calculated by the molecular dynamics method for the Coulomb and screened potentials. The static conductivity is calculated based on the collision frequency, in which screening is taken into account via the generalized Debye radius. This approach allows one to consider conductivity in a wide temperature range from a degenerate to a classical electron subsystem. Specific numerical results of the work relate to liquid metallic hydrogen, where there is no need to use potentials with adjustable parameters. The structure factors and conductivity are calculated for the Coulomb interaction between all charged particles.
