A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
AC power supplies are power supplies that use Alternating Current, which means that the current repeatedly changes its direction. AC power supplies are usually mains supplies as they are at a high voltage. Often filtering takes place between the mains supply and the device.
alternating current is easier to transfer long distances
"What is alternating current machine?"
The symbol for alternating current is: ~
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
Alternating current. Direct current is used in batteries.
A device that permits direct current (DC) and opposes the flow of alternating current (AC) is a rectifier. Rectifiers are electronic components that only allow current to flow in one direction, which is common for converting AC to DC in power supplies and other applications.
Alternating Current is measured in Amperes.
Alternating current is better than direct current for transmission.
An electrical device that converts alternating current into direct current is a rectifier. Diodes, which pass only current going one direction, are a type of rectifier. Most power supplies for electronic equipment contain rectifiers along with other components to "clean" the DC power output.
A generator produces alternating current.
