Select one:
A. Modulating current (MC)
B. Natural current (NC)
C. Direct current (DC)
D. Alternating current (AC)


Sagot :

Final answer:

Battery-powered devices run on Direct Current (DC) generated by batteries or transformers, offering a constant flow of electricity in one direction, unlike Alternating Current (AC).


Explanation:

Battery-powered devices operate on Direct current (DC) power, which is electricity flowing in a constant direction. DC is the type of electricity generated by batteries, providing a constant flow of electric charge in one direction, unlike Alternating current (AC) where the charge periodically reverses direction.

Devices like computers, cell phones, and cars utilize DC power sourced from batteries or transformers that convert AC power to DC to create a continuous flow of electric current.

One advantage of AC over DC is the ability to use transformers to adjust voltage levels easily since almost all electric power transmission is done using AC.
