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.

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. The part of an AC generator in which the voltage is produced is known as an armature.

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.

Construction of AC Generator Field- The field is composed of coils of conductors that receive voltage from the source and produce magnetic flux. What factors do the generated EMF in an alternator depend upon? What is the difference between AC generator and DC generator? Maxwell Relations. View Result. They are typically designed to conduct the flow of current from a stationary device to a rotating one. Augus Haselwander in Europe. Home Physics AC Generator. It is based on the principle of electromagnetic induction. AC Generator Diagram. A generator that converts mechanical energy into direct electrical energy i. Due to this, an emf is induced in the armature. This results in a magnetic effect of electric current flowing through the galvanometer. Working of an AC Generator When the armature rotates between the poles of the magnet upon an axis perpendicular to the magnetic field, the flux linkage of the armature changes continuously.

.

The magnetic flux in the field cuts the armature to produce a voltage. Advantages of AC Generator AC generators have a number of advantages over DC generators, including: Efficiency: AC generators are more efficient than DC generators, meaning that they can convert more mechanical energy into electrical energy. Three-Phase AC Generator — A three-phase AC generator is an electrical machine that converts mechanical power into three-phase power alternating current by the process of electromagnetic induction. What Is an AC Generator? This electric power in the vehicles and charging battery is generated in AC generators. Now that you thought about it, you might wonder how this essential energy source is generated and how it arrives at your doorstep. Transmission: AC can be transmitted over long distances with low losses using transformers. I am vidya and I have purchased the byjus courses. Slip rings are electrical connections used to transfer power to and fro from the rotor of an AC generator. AC generators are widely used and have various applications. The video will help you explore the differences between an alternating current and a direct current. The function of slip rings in an AC generator is to transfer the alternating current AC generated in the rotating armature to the stationary external circuit.
