Anomalous resistivity caused by ion acoustic turbulence is observed in a current-carrying discharge-tube plasma. Above 0.05 V/cm, which is nearly equal to a critical field predicted from an electron collision frequency, the resistivity increases in proportion to the electric field. When a magnetic field is applied to the plasma in the presence of the ion acoustic turbulence, the electron temperature rises. It is found that the electron heating is brought about by the turbulent heating.
