The option that describes direct current is:
**A current that always flows in the same direction.**
Direct current (DC) flows consistently in one direction, as opposed to alternating current (AC), which reverses direction periodically.
**A current that always flows in the same direction.**
Direct current (DC) flows consistently in one direction, as opposed to alternating current (AC), which reverses direction periodically.
