WebbWhat is Alternating Current (AC) And Direct Current (DC) and Its Applications. Both Alternating Current and Direct Current describes the two types of current flow in a circuit. In direct current, the electric charge or current flows in one direction. In alternating current, the electric charge changes direction periodically. WebbThe electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations AC and DC are often used to mean …
