Most automotive applications use DC, although the alternator is an AC device which uses a rectifier to produce DC.

What type of device produces alternating current?

A "generator" usually produces DC current. An "alternator" usually produces AC current. Older cars up to the 1960's used generators. Newer cars use alternators (simpler design) with diode rectifiers to convert the AC to DC. Batteries are DC. Some electronic circuitry (inverters) can change DC to AC.

What instruments do AC to dc current use?

I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge

Why do you still use both ac and DC?

Because some appliances work with ac current and some with dc current.

Current in cars ac or DC?

The Current in a automobile is DC, you have a battery which is dc, and your alternator produces ac current but converts it to DC inside the alternator unit which gives your battery DC power. So basically everything in your car is DC.

Does a car use DC or AC power?

What device converts dc current to ac current?

A "Rectifier" converts AC current to pulsating DC current.

Is car battery ac or DC volts?

Batteries by definition have to be DC. While u can convert DC to AC, with a device called an Inverter, none is built into a car battery. and chances are your car doesn't even have an Inverter anywhere in it. so car is DC. in addition modern cars use 12 volts, and for the record, AC and DC are not a "type of volt," they are types of current, (Direct Current, Alternating Current).

What is the sign for ac and DC current?

AC means alternating current DC means direct current there is no polarity reversal

What is the difference between ac and dc grounding?

The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.

Is their any other difference between ac and dc current?

Yes, there is. AC = Alternating Current, the direction of the current alternates, thus the name. DC = Direct Current. Things like computers need DC (they use a AC to DC converter inside the power supply to convert it) Hope that helps a bit.

Which type of current does a dc motor use?

dc stands for direct current. This can be obtained from a battery or a rectified ac (alternating current ) supply.

Does implantable defibrillator use ac or dc current?

DC, unless you run an extension cord.
