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.

Derive an expression for its total magnification. The strong magnets create a magnetic field between the magnets directed from the north pole to the south pole. Start Quiz.

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.

The applications of AC generators are listed below: Diesel-electric locomotive alternators — Locomotives need electric and mechanical power simultaneously, and this power is provided by AC generators Marine alternators — These alternators are used for generating power in marine equipment. Losses in AC generators are relatively lesser than in DC machines. A conductor coil of n turns rotates between the magnetic poles by the means of an external agent Steam, running water, etc. This can add to the cost and complexity of an AC generator system. Download the free Testbook App to grab some exclusive offers now. Armature The part of an AC generator in which the voltage is produced is known as an armature. Static Equilibrium. The prime mover could either be a diesel engine, a steam turbine, or a motor. The induced emf is such that it opposes the cause that induced it.

They are typically designed to conduct the flow of current from a stationary device to a rotating one. Generator was invented in August by British scientist Michael Faraday. The brushes and commutators wear out quickly, so the possibility of sparking and short circuits is very high. A conductor coil of n turns rotates between the magnetic poles by the means of an external agent Steam, running water, etc. Tectonic Plates Movement. This indicates the flow of an alternating current through the galvanometer. It is given as negative of rate of change of magnetic flux through the circuit. The transmission link size in AC Generators is thinner because of the step-up feature. This voltage is the output voltage of the AC generator. A generator that converts mechanical energy into alternating electrical energy i. Find the instantaneous value of the emf induced in the rod.
