Electrical Engineering Fundamentals

Direct Current (DC)

Definition

An electric current that flows continuously in one direction through a circuit, maintaining constant polarity at each terminal. Batteries, photovoltaic panels, and fuel cells produce DC natively; most electronic equipment operates on DC internally. Bulk AC transmission systems use DC only in specialized applications such as high-voltage direct current (HVDC) links for long-distance or asynchronous interconnections, where power electronics convert between AC and DC at each terminal.
