Abstract
For the Fokker-Planck-equation for a plasma the system of moment equations is derived. The highest order moments considered are the components of the heat flux. For these the condition must be satisfied that they are small compared with (5/2) p √p/ϱe. All moments of lower order, especially the difference velocity of electrons and ions (i.e. the electrical current) and the anisotropy of pressure are arbitrary in this approximation.Keywords
