Direct current flows in which direction?

  1. One direction

  2. Multiple directions

  3. A circular motion

  4. No specific direction

The correct answer is: One direction

Direct current flows in one direction because it is the movement of electric charge in a single direction. This is in contrast to alternating current which changes direction periodically. The other options are incorrect because they do not accurately reflect the nature of direct current. Multiple directions and a circular motion do not describe direct current as it is always flowing in one direction. No specific direction is also incorrect as direct current has a specific and consistent flow in one direction.
