What does the acronym DC stand for?

The acronym DC stands for Direct Current. This type of electrical current flows in a single direction, as opposed to alternating current (AC), which periodically reverses direction. In direct current, the electric charge moves steadily from the negative terminal to the positive terminal, providing a consistent voltage over time. This characteristic makes DC suitable for many electronic devices and batteries, as they require a stable voltage to operate effectively. Understanding this distinction is important in electrical theory and application, as different devices and systems may use either DC or AC depending on their design requirements.
