Spitzer resistivity

Spitzer resistivity is a classical model of electrical resistivity, η , that is based upon electron-ion collisions. It is given by

where Z is the ionization of nuclei, m is the electron mass, ε 0 is the electric permittivity of free space, ln ⁡ Λ is the Coulomb logarithm, k B is Boltzmann's constant, and T is the temperature in kelvins.

This resistivity model was proposed by Lyman Spitzer.

Spitzer resistivity is commonly used in plasma physics.
