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. The first AC generator was developed in by F. Augus Haselwander in Europe. The AC generator works on the principle of Faraday's law of electromagnetic induction. The armature in the AC generator rotates between the poles of the magnet upon the axis perpendicular to the magnetic field.

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.

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.

Difference Between Kva And Kw. Transmission: AC can be transmitted over long distances with low losses using transformers. Draw a diagram of AC generator and describe it. Explore SuperCoaching Now. The flux linkage of the armature changes continuously. Brushless alternators —These alternators are the main source of power in electrical power plants. 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. Test your knowledge on AC Generator Q 5. Cost: AC generators are generally less expensive than DC generators of the same capacity. Then, angle between surface area vector of the coil and the magnetic field after time t is given by:.

Byjus has helped me a lot in improving my core subjects. The strong magnets create a magnetic field between the magnets directed from the north pole to the south pole. 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. Describe the construction of a compound microscope. The output is generated in the armature. Thank you byjus. AC generators are widely used and have various applications. When the external circuit is closed, an alternating current flows through the coil and hence, electrical energy is supplied to the circuit. Slip rings and brushes. The field consists of coils of conductors that receive a voltage from the source and produce magnetic flux.
