Ac generator class 12 diagram

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. A generator that converts mechanical energy into alternating electrical energy i. The emf generated is dependent on the number of armature coil turns, magnetic field strength and the speed of the rotating field. AC generators are based on the principle of Faraday's law of electromagnetic induction.

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.

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 slip rings are made of metal and are insulated from each other.

Draw a ray diagram for the formation of image by a compound microscope. The emf generated is dependent on the number of armature coil turns, magnetic field strength and the speed of the rotating field. They are typically designed to conduct the flow of current from a stationary device to a rotating one. AC generators are based on the principle of Faraday's law of electromagnetic induction.

The brushes have high-efficiency chances of a short circuit is very unlikely The brushes and commutators wear out quickly, so the possibility of sparking and short circuits is very high. Where AC generator is used? Augus Haselwander in Europe. Rotor The rotating component of the generator is known as a rotor. The output is an alternating electrical power in the form of alternating voltage and current. Report An Error. The brushes and commutators wear out quickly, so the possibility of sparking and short circuits is very high. Vidya May 29, at am.

This component primarily consists of coils of wire that are large enough to carry the full-load current of the generator. Watch Now. The stator core comprises a lamination of steel alloys or magnetic iron to minimise the eddy current losses. When the external circuit is closed, an alternating current flows through the coil and hence, electrical energy is supplied to the circuit. They gave me a immediate response whenever I had some doubts. View Test Series. Slip rings and brushes. Read More: Eddy Current. The strong magnets create a magnetic field between the magnets directed from the north pole to the south pole. Start Quiz.
