Voltage
When electric current changes direction, it is called alternating current (AC).
An electric current that changes direction is called an alternating current (AC). In an AC circuit, the flow of electrons changes direction periodically, typically at a frequency of 50 or 60 Hz. This is in contrast to direct current (DC), where the flow of electrons is constant in one direction.
A device that changes the direction of the current is called a "switch" or a "reversing switch." This device allows for the current to flow in different directions as needed.
DC (direct current).
When a surface current deflects, it changes direction.
Direct current (DC) is the term used to refer to current that flows in one direction and does not reverse its direction. This is in contrast to alternating current (AC), which changes direction periodically.

alternating current (ac)
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
A current which changes its direction of flow again and again is known as alternating current.
