Complete answer: AC generators are used in the power stations. AC generator and DC generator both use electromagnetic induction to generate electricity.
Do power plants use AC or DC generators?
Alternating current (AC) is the type of electric current generated by the vast majority of power plants and used by most power distribution systems. Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances.
What type of generator is used in power plants and portable electric generator?
There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
What are DC generators used for?
Applications of DC Generators
These generators are used to charge batteries, provide lighting and provide excitation to alternators. They are used to provide field excitation current for regenerative braking in DC locomotives. They are used in DC motors where speed control is necessary.
What are the 3 types of generators?
There are three basic types of generators: whole house generators, portable generators and inverter generators.
- Inverter generators are ideal for camping, boating and other recreational activities. …
- Whole house generators (home standby generators) are the best generators for home use.
What is types of generator?
There are three main types of generators: portable, inverter and standby.

What are DC generators?
A direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current. … The field is produced by direct current in field coils or by permanent magnets on the stator. The output, or armature, windings are placed in slots in the cylindrical iron rotor.
What voltage is a generator?
Home standby generators and most portable generators can supply either 120 volts or 240 volts and do it at the same time. Different voltages make it important to understand why we rate generators in watts. In terms of capacity, it is the power in watts that matters.
What is the example of DC generator?
The alternator in a car (i.e., the DC generator which recharges the battery) is a common example of a DC generator of the type discussed above. Of course, in an alternator, the external torque needed to rotate the coil is provided by the engine of the car. Figure 42: Emf generated in a steadily rotating DC generator.
