GEOLOGY

Detailed explanation-1: -Direct current is the one which flows only in one direction and we get this from batteries.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. Most students of electrical engineering and related subjects begin their studies by learning about direct current (DC).

Detailed explanation-5: -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.
