** Explain the construction and working of an electric generator (AC). Draw a neat diagram and label it.

The diagram of AC generator is shown in the attached diagram. Construction: Two fixed strong permanent magnets are placed with their opposite poles facing each other. The magnetic field …

Draw a labelled diagram of an ac generator. Obtain the expression for the emf induced in the rotating coil of N turns each of cross-sectional area A, in the presence of a magnetic field → B.

When the armature coil is rotated in the strong magnetic field, the magnetic flux linked with the coil changes and the current is induced in the coil, its direction being given by Fleming's right …

Alternating current generators, typically referred to as AC generators, generally work on the same principle as direct current generators.The basic function of a generator is to convert motion …

Question (a) State the principle of an ac generator and explain its working with the help of a labelled diagram. Obtain the expression for the emf induced in a coil having N turns each of …

Working of an AC generator: According to the Faraday's law of electromagnetic induction, whenever a conductor moves in a magnetic field EMF gets induced across the conductor. If …
