Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
Direct Current Definition: Direct current is a constant and unidirectional flow of electric charge, moving from a negative to a positive terminal.
Direct Current (DC) is a type of electric current that flows in only one direction. It is the opposite of Alternating Current (AC), which periodically changes direction.
The meaning of DIRECT CURRENT is an electric current flowing in one direction only and substantially constant in value —abbreviation DC.
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.
Direct current, ordinarily abbreviated as DC, refers to the progression of electric charge in a constant direction. As opposed to alternating current(AC), where the electric charge occasionally takes a different path, DC keeps a reliable flow in one direction.
Electrical current is the flow of charged particles, or specifically in the case of AC and DC, the flow of electrons. According to Karl K. Berggren, professor of electrical engineering at MIT, the fundamental difference between AC and DC is the direction of flow.
Direct Current circuit is an electrical circuit in which Electric Current flows through in one direction. In a DC Circuit there are components like DC battery, switch, connecting wires, resistors and ammeter and voltmeter.
Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change.
direct current, flow of electric charge that does not change direction. Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators.
