Final answer:
A constant, even-flowing electrical current that travels in one direction is called direct current (DC), which maintains a steady voltage and is used in many devices. so, option c is the correct answer.
Step-by-step explanation:
An even-flowing electrical current that travels in one direction only is called direct current (DC). Direct current is used in various applications, such as the electrical systems of automobiles. Unlike alternating current (AC), which reverses direction at regular intervals, direct current maintains a constant flow of electric charge in one direction. This ensures that devices which require a steady voltage and current, such as electronic circuits that are found in computers and other sensitive equipment, operate efficiently.
Direct current (DC) is a constant, even-flowing electrical current that travels in one direction only.
The constant, even-flowing electrical current that travels in one direction only is called Direct current (DC). Direct current refers to the flow of electric charge in only one direction. It is characterized by a constant magnitude and does not change its direction at regular time intervals.
