That is called "DC" or "direct current".
A direct current involves change of flow in a single direction.
A direct current involves change of flow in a single direction. DC (direct current), at least on the macro scale. On the atomic scale, they seem to wander all over the place between atoms, and the average movement is what we measure as current.
the movement of electrically charged particles, atoms, or ions, through solids, liquids, gases, or free space; the term is usually used of relatively smooth movements of electric charge through conductors, whether constant or variable. Sudden movements of charge are usually referred to by other terms, such as spark or lightning or discharge. In metallic conductors the electric current is usually due to movement of electrons through the metal. The current is measured as the rate of movement of charge per unit time, and is counted in units of amperes. As a formal definition, the direction of movement of electric current is considered as the same as the direction of movement of positive charge, or in a direction opposite to the movement of negative charge. Electric current may move constantly in a single direction, called direct current (abbreviated DC), or may move alternately in one direction and then the opposite direction, called alternating current (abbreviated AC).

Gravity
DC (direct current, a current that flows in a single direction).
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

An Electric Current :)
That is called an electrical current, or just a current.
If the current flows only in one direction, it will flow for a very short time - due to the electric charge that builds up. For example excess electrons will build up on one side, and stop any further electrons from coming in.
"DC" simply means that the voltage, and the current, goes in a single direction.
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
