Is a car battery AC or DC?

in Electrical Engineering

Is a car battery AC or DC?

1 Answer

A car battery provides **DC (Direct Current)** power. The battery stores electrical energy and delivers it as a steady flow of current in one direction, which is characteristic of DC.

Most electrical systems in a car, like the lights and electronics, run on DC power from the battery. However, the car's alternator (which charges the battery while the engine is running) produces AC (Alternating Current) power, but it is converted to DC before being stored in the battery.
