DC GERATORS PRODUCE DC current with the help of spilt ring commutators.
An a.c. generator produces alternating current, whereas a d.c. generator produces direct current.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
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.
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.

Converting D/C into A/C is very expensive. You can use inverters to switch the direction of the current but you would probably be better off to replace your DC generator with an AC generator and if you need both AC and DC power then use a rectifier (inexpensive when compared to inverters) to convert the AC to a DC current.

current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.
1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.
"AC" is just a scientific term that refers to the fact that this generator produces electricity in an Alternating Current as opposed to "DC" which refers to Direct Current. Commonly, the plug outlet on the wall is AC, and the little black box electrical adapter for your cordless telephone is changing that AC current into DC current for the phone to work on. The phone line in your house runs on 24 volts DC, where the wall sockets are 124 volts AC.
An alternator produces AC current but it is converted to DC by the rectifier inside the alternator.
