Detailed explanation-1: -Direct current (DC) is electrical current which flows consistently in one direction. The current that flows in a flashlight or another appliance running on batteries is direct current.

Detailed explanation-2: -Direct current refers to the unidirectional propagation of electric charge. It is commonly used in batteries and solar cells. Thomas Edison invented DC current, which allowed him to power numerous complex electrical systems.

Detailed explanation-3: -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.

Detailed explanation-4: -There are two types of electricity: direct current and alternating current. There are two methods of electric current. These are direct current (DC) and alternating current (AC). Direct current is a method in which electricity always flows in a certain direction, as compared to the flow of a river.

Detailed explanation-5: -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.
