What type of current flows continuously in the same direction?

Direct current (DC) is the type of current that flows continuously in the same direction. This means that the electric charge or current moves from the negative terminal to the positive terminal without changing direction over time. This unidirectional flow is typical in batteries and other DC power sources.

The consistency in direction means that devices powered by direct current often have simpler circuitry, as there’s no need to accommodate changes in polarity. This is in contrast to alternating current (AC), which periodically reverses direction, and can be more complex to manage in terms of applications that require steady and reliable power flow. Understanding the characteristics of direct current is crucial for various electronic and electrical applications, particularly where stable voltage and current are essential for proper function.
