How do electrons move to create a direct current?

Electrons create a direct current by moving in one direction, establishing a consistent flow of electric charge. In a direct current (DC) circuit, the electrons travel steadily from the negative terminal of the power source to the positive terminal, without changing direction. This unidirectional flow is essential for powering devices that require a constant voltage, such as batteries, electronic circuits, and many household appliances.

The other movement patterns described in the other choices, such as alternating directions or circular or zigzag patterns, are characteristic of different types of electricity. For instance, alternating current (AC) involves electrons oscillating back and forth, which is not suitable for applications that require a stable, flowing current like that produced in DC systems. Therefore, the consistent and steady movement of electrons in one direction is what defines and enables the operation of direct current.
