In which direction does direct current travel in a conductor?

Direct current (DC) travels in one direction through a conductor. This is a fundamental characteristic of DC, where the flow of electric charge is consistent and unidirectional, typically moving from the positive terminal to the negative terminal. This unidirectional flow is crucial for many applications, such as in batteries and DC power supplies, where stable and predictable voltage is necessary.

In contrast, alternating current (AC) changes direction periodically, which is not the case with direct current. Understanding that DC flows in a single direction helps clarify its use in various electronic devices and circuits, reinforcing the concept of flow that is essential for electrical systems design and analysis. This characteristic also simplifies calculations related to current, voltage, and resistance in circuits utilizing direct current.
