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.
1.DC motors are direct current motors while ac motors are alternating current motors. 2.DC motors generally characterize a continual and standard current flow while AC motors are used in variant situations irrespective of the quality of the current flow.
