direct current

Direct current (DC) is an electric current that flows in a single, constant direction. Unlike alternating current (AC), which periodically changes direction (like in household power outlets), DC provides a steady flow of electricity, similar to the power from a battery. This consistent flow makes DC ideal for powering devices like smartphones, laptops, and electric vehicles. It’s often used in electronic circuits and systems where stable, predictable voltage is required. DC’s simplicity in flow allows for efficient storage in batteries and direct use in many low-voltage electronic applications.
