Final answer:
True. The power supply does convert the wall outlet AC power into DC power.
Step-by-step explanation:
True
The power supply converts the wall outlet AC power into DC power.
Devices that use AC, such as vacuum cleaners, fans, power tools, and hair dryers, obtain power from the wall socket which provides an alternating potential. On the other hand, devices that use DC, like computers, cell phones, flashlights, and cars, obtain power from a battery or a transformer that converts AC potential to DC potential.
A transformer, often called a charger or a battery, is used to convert AC voltage to DC voltage for electronic devices like laptops and cell phones.
