Spitzer Resistivity

Wikipedia Article

The Spitzer resistivity describes the electrical resistance in a plasma.

$$\mu \_Sp=\frac{4sqrt(2\pi )}{3}\frac{Z{e}^{2}m\_e^{1/2}ln\Lambda }{(4\pi ϵ\_0{)}^2(k\_BT\_e{)}^{3/2}}$$

• $Z$ is the ionization of the nuclei
• $e$ electron charge
• $m\_e$ electron mass
• $\Lambda$ is the Coloumb logarhytm
• $ϵ\_0$ electric permittivity of free space
• $k\_B$ Boltzmann constant
• $T\_e$ is the electron temperature in Kelvin

• Resistivity decreases in proportion to rising electron temperature as $T\_e^{-3/2}$.
