What does the abbreviation 'DC' stand for?

The abbreviation 'DC' stands for "Direct Current." This term refers to the unidirectional flow of electric charge, typically used in applications where a constant voltage or current is required, such as in batteries and electronic devices. In direct current, the electric charge flows in one direction, which is distinct from alternating current (AC), where the flow of charge periodically reverses direction. Understanding direct current is vital in various fields, including electronics and electrical engineering, as it helps in designing circuits and understanding power supply systems.
