Alternator current, which is alternating current (AC), is converted to direct current (DC) by a component called a rectifier. The rectifier typically consists of diodes that allow current to flow in only one direction, effectively blocking the negative half of the AC waveform. This process results in a pulsating DC output, which can be further smoothed with filters to produce a more stable DC voltage suitable for charging batteries or powering DC devices.

How does an altanator work?
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.
What does an alternator diode rectifier do?
The alternator diode rectifier converts the AC current being produced by the alternator to DC from which most of the electronics installed and battery use.
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 charges the car's battery?
The battery is constantly being charged by the alternator as long as the engine is running. The alternator is driven by a fan belt or serpentine belt and provides a consistent steady flow of direct current of around 14 or 15 volts. The amount of voltage is kept steady even at varying engine revolutions by a voltage regulator.
What could drain the power from the battery within 24 hrs after installing a new alternator and battery?
Bad starter.. direct ground..... stero equipment IG: amplifier being improperly wired . and it is possible to have the wrong alternator or a faulty one.

Why alternating current cannot be stored in battery?
Batteries store electrical energy in the form of chemical energy. Alternating current (AC) constantly changes direction, which makes it unsuitable for direct storage in a battery, which requires a constant flow of electrons in one direction to charge. However, AC can be converted to direct current (DC) before being stored in a battery.
Alternator not charging on a 1999 Camaro Previous owner put a jumper wire from the MAP sensor to provide current to the alternator when jumper is removed alternator stops charging?
It depends on where the wire is being connected on the alternator. It could be the alternator or it could be a damaged wire or connector. It's something that you will need to track down.
Did Thomas Edison want direct current or alternating current?
Thomas Edison promoted direct current (DC) as the preferred method of electrical distribution. He believed DC was safer, cheaper, and more efficient than alternating current (AC) which was being championed by his rival, Nikola Tesla.
Are there examples of DC running locomotives being converted to AC running?
Direct Current is used in locomotives because it is the most efficient way of getting electricity to work in the loco. Alternating Current is used in homes and businesses and factories because it can be made in one place and sent long distances to be used in a different place
How can i tell if alternator is not working on a 2002 ford focus?
Usually the appropriate warning light on the dash will come on if the alternator is not producing current. If you don't trust the warning light, take a volt/ohm meter and (making sure it is set on the DC reading scale) connect it across the output terminals of the alternator to determine if any current is being produced.
When the alternator is charging battery will the alternator gauge indicate D or C?
The D indicates the discharge side of the guage, and when the indicator needle is located anywhere in this area indicates that the alternator is not creating enough current to charge the battery, and therefore, the battery is being discharged. The C indicates the charge side of the guage, and when the needle is in this area, it means the alternator is putting out enough current to charge the battery. A needle right in the center indicates that the current going into the battery equals the amount of current being taken from the battery by your vehicle's electrical devices. The closer to the center, the lower the amount of current is flowing, and conversly, the farther to the edge [closer to the D or C] the greater the amount of current flowing, whether it's a charging flow, or a discharging flow. Therefore, when the battery is being charged, the needle should be somewhere between the center [no flow] and the C.The closer to the C, the greater the rate of charge to the battery.
Explain why a 24v system that runs off of 4 batteries which includes a 12v feed- that's powered by two of the batteries are getting no charge from the alternator.. the other two are charged well.?
With the batteries in series, the alternator provides the same current, and therefore the same charge to all the batteries. The alternator can take no account of any current being drawn from the 12V take off point. Part of the charge current is being fed to the 12V load and not to the batteries. Therefore, the 12-24V batteries are being fully charged while the 0-12V batteries are being partially charged. Over a period of time, the difference between the charge levels will become more obvious.
