Electric current can flow through a continuous path which can also  be described as a closed circuit. Conversely, any break or opening  in a circuit is called an open circuiâ¦t. Charges can only flow  through a closed circuit.
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.
