An electric machine that converts mechanical energy into electrical energy in the form of voltage and current is known as a generator. It is based on the principle of electromagnetic induction. Generator was invented in August by British scientist Michael Faraday. It was known as the Faraday Disk. Generators are of two kinds: AC generator and DC generator. An AC generator is a machine that converts mechanical energy into electrical energy in the form of alternating current AC. In this article, we will be studying about AC generators, the working principles of AC generators, types, and uses of AC generators.

From flipping a switch to heating a snack in the microwave, electricity is everywhere. Now that you thought about it, you might wonder how this essential energy source is generated and how it arrives at your doorstep. Electricity is produced in power stations using turbines and generators. A turbine converts available energy into rotation while electric generators convert rotation into electricity. This article will discuss the working principle and parts of an AC generator in detail. You can visit our article on DC Generator if you are interested to learn about the working principle and characteristics of a DC generator. AC generator is a machine that converts mechanical energy into electrical energy. The output is alternating electrical power in the form of alternating voltage and current. This can either be achieved by rotating a conducting coil in a static magnetic field or rotating the magnetic field containing the stationary conductor. The preferred arrangement is to keep the coil stationary because it is easier to draw induced alternating current from a stationary armature coil than from a rotating coil. The generated EMF depends on the number of armature coil turns, magnetic field strength, and the speed of the rotating field. The field consists of coils of conductors that receive a voltage from the source and produce magnetic flux. The magnetic flux in the field cuts the armature to produce a voltage. This voltage is the output voltage of the AC generator.

As the coil rotates, the angle between the magnetic field and the coil changes which leads to the generation of an alternating induced emf.

How does the electric supply get into your house? The answer to this is the AC Generator. But have you seen an ac generator working? And do you know how does the mechanism behind it? Well, let us study this more in detail. An AC generator is an electric generator that converts mechanical energy into electrical energy in form of alternative emf or alternating current. An Ac generator consists of two poles i. There is also a coil which is rectangular in shape that is the armature. These coils are connected to the slip rings and attached to them are carbon brushes.

The first AC generator was developed in by F. This magnetic flux in the magnetic field cuts the armature to produce a voltage. Your result is as below. Yes, an AC generator can be converted into a DC generator by using half-split slit rings. Gauss Theorem. Transmission: AC can be transmitted over long distances with low losses using transformers. Start Quiz. What is the difference between AC generator and DC generator? Armature- Armature consists of wire coils, large enough to carry full load current for the generator. Download as PDF. The strong magnets create a magnetic field between the magnets directed from the north pole to the south pole.

This type of current is called an alternating current or an AC. Simplicity: AC generators are simpler to design and build than DC generators. When the external circuit is closed, an alternating current flows through the coil and hence, electrical energy is supplied to the circuit. What is the function of slip rings in AC generator? Tectonic Plates Movement. The magnetic flux in the field cuts the armature to produce a voltage. AC generators are widely used and have various applications. Field The field consists of coils of conductors that receive a voltage from the source and produce magnetic flux. This component primarily consists of coils of wire that are large enough to carry the full-load current of the generator. The prime mover could either be a diesel engine, a steam turbine, or a motor.
