Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.
The left-hand side of the full-wave rectifier circuit consists of four diodes: a diode bridge. Half-wave current is a current that can only flow in alternate current, a full-wave current can flow both alternating current and direct current. rectifier is a device that can convert Alternating current (AC) to Direct current (DC). This is a process called rectification.
