Final answer:
Direct Current (DC) is the type of current that flows from the negative terminal to the positive terminal in a single direction.
Step-by-step explanation:
The current that flows from the negative (-) terminal to the positive (+) terminal in a single direction is called Direct Current (DC). In a DC circuit, electrons flow through the circuit from the negative terminal to the positive one, providing a constant and unidirectional flow of electric charge. Unlike Alternating Current (AC), where the flow of electric charge periodically reverses direction, DC maintains a constant voltage and current direction, commonly used in battery-powered devices.
