A C Generator (Alternator) - Construction And Working: NOTE : This article is about alternator. The term 'AC generator' commonly refers to 'alternator'. Read about 'Induction Generators' here. An alternator is an electrical machine which converts mechanical energy into alternating electric energy. They are also known as synchronous generators. How Does An AC Generator Work? The working principle of an alternator or AC generator is similar to the basic working principle of a DC generator. Above figure helps you understanding how an alternator or AC generator works.  According to the Faraday's law of electromagnetic induction, whenever a conductor moves in a magnetic field EMF gets induced across the conductor. If the close path is provided to the conductor, induced emf causes current to flow in the circuit. Now, see the above figure. Let the conductor coil ABCD is placed in a magnetic field. The direction of magnetic flux will be form N pole to S pole. The co
