Using the kinetic equation with BGK (Bhatnagar-Gross-Krook) collision integral and taking into account the relaxation of electron density and temperature, the low-frequency instability of a constant-current carrying discharge is investigated in a weakly ionized and nonmagnetized plasma. It is shown that this instability is caused by the stimulated scattering of drifting electrons from the relaxation oscillations of the electron temperature.
