What does “DC” stand for in electrical terms?

In electrical terminology, “DC” stands for Direct Current. This refers to the unidirectional flow of electric charge, which means that the current moves in a single direction. Direct current is commonly used in various applications, including batteries, electronic devices, and low-voltage power supplies. It contrasts with alternating current (AC), where the direction of the current periodically reverses. Understanding direct current is fundamental in electronics, as it is essential for the operation of many electronic components and circuits, which rely on stable and consistent voltage levels to function properly.
