Automotive electrical systems are what types of current?

Explanation:
Automotive electrical systems run on direct current. The battery provides DC voltage, and almost all vehicle components—lights, starters, sensors, and control modules—are designed to operate from a steady DC supply. The alternator, while it generates AC on its windings, uses diodes (a rectifier) to convert that AC to DC and a regulator to keep the system voltage around 13–14 volts when the engine is running. So the power delivered to the car’s circuits is direct current. Some signals in the system may be modulated (pulsed) through switching for efficiency, but the overall supply remains DC.
