Spitzer resistivity
The Spitzer resistivity (or plasma resistivity), also called 'Spitzer-Harm resistivity', is an expression describing the electrical resistance in a plasma, which was first formulated by Lyman Spitzer in 1950. The Spitzer resistivity of a plasma decreases in proportion to the electron temperature as T e − 3 / 2 {\displaystyle T_{\text{e}}^{-3/2}} .
