What is an alternator for?
The alternator generates power to run the car and charge the battery. An alternator in a vehicle generates Alternate Current (AC) instead of Direct Current (DC) electricity to power the vehicle.
How does the alternator recharge the battery?
An alternator is just a small generator that generates AC power and is converted to 12v DC power via a transformer for battery storage and use.
Is there DC alternator?
An alternator is a device that converts DC (direct current) to AC (alternating current). If you need to convert AC to DC, then you need a rectifier.
How do you convert a DC generator to ac alternator?
Turn the DC generator inside out and you have an alternator .
Is an alternator and a starter the same?
No, and alternator generates DC current. A starter just uses DC current to start the engine.
Does a motor car emit ac or dc?
The engine itself emits nothing. The alternator does. The alternator emits AC, but it is converted to DC.
Is a car electrics dc or ac?
Car electrics use DC current. Based around the storage of electricity in a 12v battery. Modern vehicles charge the battery, and supply power when running, using an alternator. Although the alternator generates AC, for efficiency, it is converted to DC straight away, before being applied to the rest of the circuitry.
What device changes ac to dc in an alternator?
diode
What kind of electricity does an alternator make DC or AC?
It makes AC ( alternating current ) . That's why it's called an alternator. A DC generator would usually be called a dynamo.
What would cause the volt meter on 1994 Le Sabre to bounce up and down.?
It could be the alternator. Unlike the old generators that generated a DC voltage, the alternator generates an AC voltage. Diodes are used to convert this to a DC voltage. If a diode fails, the AC voltage will come through. Many auto parts stores can check the alternator while it is in the car. That is the first thing I would check.
How do you take both ac and DC from car alternator?
An Alternator produces AC (the clue is in the name) Alternating Current.Add in a Bridge rectifier, and it produces DC (Direct current).Basically the alternator "alternates" or switches the voltage, and the rectifier switches the opposite way, in perfect time, turnign the AC into DC.
What generates more noise ac motor or dc motor?
dc motors generate more noise.
