A generator produces electricity by moving wires through a magnetic field. The direction of the induced current is dependent upon the direction in which the wire crosses the magnetic field. In a generator the magnetic field is usually fixed - and the wires are spinning through it. So: Visualize a horizontal magnetic field. The axis of rotation of the wires is perpendicular to the field. Any given wire will be cutting up through the field at a given point... then, 180º later will be cutting down through the same field. The direction of the induced current will reverse with each half-rotation because the wire will be moving in the opposite direction relative to the magnetic field.
(In the USA the generators produce "60 cycle" current. That tells you that the generators are turning their wires (coils) at 60 revolutions per second.)

To increase the size of the current the generator produces, you can increase the strength of the magnetic field, increase the speed of rotation of the generator, or increase the number of turns in the generator coil. These factors all contribute to the overall output of the generator.
A generator produces electrical energy through the conversion of mechanical energy, typically created by a turbine being turned by flowing water, steam, wind, or combustion of fuel. This mechanical energy is transformed into electrical energy through electromagnetic induction.
A basic generator always creates an AC current, but some generators take the AC current and converts it to DC, such as a car's alternator to charge your battery. A DC current can also be converted into AC power, such as a car equipped with a household outlet. ADDED: It's not the alternator itself that produces the d.c. for a car's electrical system, but a rectifier. This is normally located within the alternator casing, but electrically it is still a separate component that converts the alternator's output.
A 5.5 kW generator produces 5,500 watts of power. This is the maximum power output that the generator is capable of producing under optimal conditions.
The turbine is solidly connected to the generator, which is similar to a very large AC generator that you have in a car, but produces a high voltage output, usually something like 20 kV. The whole assembly rotates at a rate to produce either 50 Hz or 60 Hz AC depending on the system it is part of.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
An a.c. generator produces alternating current, whereas a d.c. generator produces direct current.
The stator and the magnets.
An electric device that produces an electric current that reverses direction many times per second. Also called a synchronous generator.
what is the construction of ac generator
There are two types of electrical generator. One is a dynamo, which produces d.c. The other is an alternator, which produces a.c.
Alternator and ac generator is equal
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.
An AC generator, or alternator, is a device that converts mechanical energy into electrical energy through electromagnetic induction. It produces alternating current (AC) by rotating a coil within a magnetic field, which induces an electric current that changes direction periodically. The frequency of the generated AC depends on the speed of rotation and the design of the generator. AC generators are widely used in power plants and various applications, providing electricity for homes and industries.
DC generator
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
DC GERATORS PRODUCE DC current with the help of spilt ring commutators.
