The electric current flows only in one direction.
A
Ohm’s Law
B
Electric Current
C
Direct Current (DC)
D
Alternating Current (AC)
Explanation: 

Detailed explanation-1: -Direct current is produced when electrons flow constantly in one direction. It’s abbreviated as “DC". Since direct current flows in one direction only, its electrical pressure or voltage is always oriented in one direction, or “polarity".

Detailed explanation-2: -Direct current is the one which flows only in one direction and we get this from batteries.

Detailed explanation-3: -Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.

Detailed explanation-4: -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. It is used in many household electronics and in all devices that use batteries.

Detailed explanation-5: -A magnetic field near a wire causes electrons to flow in a single direction along the wire, because they are repelled by the negative side of a magnet and attracted toward the positive side. This is how DC power from a battery was born, primarily attributed to Thomas Edison’s work.
