Question

Explain the principle and rule involved in the working of a generator, if it is produced alternating current.

Answer 1

Answer:

An AC generator is an electric generator that converts mechanical energy into electrical energy in form of alternative emf or alternating current. AC generator works on the principle of ”Electromagnetic Induction”.

Working of an AC Generator

When the armature rotates between the poles of the magnet upon an axis perpendicular to the magnetic field, the flux which links with the armature changes continuously. Due to this, an emf is induced in the armature. This produces an electric current through the galvanometer and the slip rings and brushes.

The galvanometer swings between the positive and negative values. This indicates that there is an alternating current flowing through the galvanometer.
