DC from the vehicle battery.
Alternative AnswerModern vehicles use alternators -in other words, A.C. generators- to charge their battery. This is achieved using a rectifier, which converts the A.C. into D.C.
It doesn't have to be rectified. That's the ONLY advantage; the electrical systems in all but the smallest planes are 400Hz AC systems.
An alternator works by converting mechanical energy from the engine into electrical energy that charges the battery and powers the electrical systems in a vehicle. It consists of a rotor spinning inside a stator with wire windings, creating an alternating current (AC) that is converted into direct current (DC) by diodes before being sent to the battery and electrical components.
AC voltage, or alternating current voltage, is a type of electrical power where the flow of electricity periodically changes direction. This change in direction allows for the efficient transmission of electricity over long distances. AC voltage is commonly used in electrical systems for powering homes, businesses, and industrial equipment. It is also used in devices such as appliances, electronics, and lighting fixtures.
AC current, or alternating current, works in electrical systems by constantly changing direction, flowing back and forth in a circuit. This movement of electrons creates a changing magnetic field, which allows for the efficient transmission of electricity over long distances and through various devices.
DC is generally considered safer than AC in terms of electrical systems because DC does not cause the same level of electric shock and is less likely to start fires.
Car electrical systems are DC, direct current.
FACTS = "Flexible AC Transmission Systems".
The father of alternating current (AC) is Nikola Tesla. He developed the AC electrical system and made significant contributions to the design of AC motors and transformers. His work laid the foundation for modern electrical power distribution systems, which use AC to transmit electricity efficiently over long distances. Tesla's innovations have had a lasting impact on the way electricity is generated and used today.

AC power, or alternating current power, works in electrical systems by constantly changing direction, flowing back and forth in a circuit. This flow of electricity is generated by power plants and transmitted through power lines to homes and businesses. AC power allows for efficient distribution of electricity over long distances and is used to power a wide range of devices and appliances.
When working with AC electrical systems, it is important to be cautious of the higher voltage levels and the potential for electric shock. DC systems typically have lower voltage levels but can still pose a risk of shock. Both systems require proper insulation, grounding, and protective equipment to prevent accidents. It is crucial to follow safety guidelines and procedures when working with either AC or DC electrical systems to minimize the risk of injury or damage.
Air conditioning systems for structures don't use the same refrigerants as vehicle AC systems do. Your AC system probably uses R22.
