What does the abbreviation DC stand for in electrical terms?

In electrical terms, the abbreviation DC stands for Direct Current. This type of current is characterized by the flow of electric charge in a single direction, which distinguishes it from alternating current (AC) where the flow periodically reverses direction. Direct Current is widely used in various applications such as batteries, solar panels, and electronic devices that require a steady, constant voltage. Understanding this concept is critical for anyone studying electrical theory or working with electronic circuitry, as it lays the foundation for comprehending how different types of current affect circuit design and functionality.
