In a plasma, the Boltzmann relation describes the number density of an isothermal charged particle fluid when the thermal and the electrostatic forces acting on the fluid have reached equilibrium. Due to their small mass and larger mobility, in many situations the electron density of a plasma is assumed to behaves according to the Boltzmann relation.
