The temporary characteristics of current and voltage of an underwater face discharge are compared at ignition on alternative and pulsating currents. It is demonstrated that electric characteristics of an underwater discharge at alternative and pulsating currents are the same in the two known combustion regimes. The values of the potential drop at the gas discharge and of the discharge current at transition from one active mode to the other are determined. The current-voltage characteristics of discharge combustion at alternating and pulsating currents are compared. It has been established that they are curves of a closed type and of elliptical shape. It means that the regime of combustion is oscillatory.
