Final answer:
Computers require direct current (DC) for power.
Step-by-step explanation:
Computers require direct current (DC) for power. This statement is TRUE. Direct current is the flow of electric current in only one direction. It is the steady state of a constant-voltage circuit. Computers, along with other devices like cell phones, flashlights, and cars, use DC for power. This can be provided by a battery, which provides a constant potential or by using a transformer to convert AC potential to DC potential.
Power for computers comes from direct current (DC). In order to meet the power requirements of the internal components and peripherals, a computer's power supply unit converts the alternating current (AC) from the wall outlet into direct current (DC) voltage.
