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.
Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric charge flows in a constant direction, distinguishing it from alternating current (AC).
