Direct Current (DC), is divided into the constant current and the pulse current.

-The magnitude (voltage level) and direction (positive and negative) of the constant current do not change with time (within relative range), such as dry batteries.

-The direction (positive and negative) of the pulse DC current is constant, but the magnitude changes with time, such as the output current of the half-wave rectifier.
