Chapter 25, Problem 33A

To determine

To Explain: The major parts of an AC generator.

Explanation of Solution

Introduction:

An AC generator is a type of electrical generator that is used to convert the mechanical energy into the electrical energy as alternating current. The working of an AC generator takes place on the principle of electromagnetic induction.

In an AC generator,slip ring device is used in which one end of the wire is connected to the armature and the other ring is connected to the remaining end of wire. As there is rotation of wire in the magnetic field at 180 degrees the EMF reverse its direction.

There are various components that forms the AC generator. In this, there is a permanent magnet which is a type of magnet that retains its properties of the magnet even when there is no current or inducing field.

There is a slip ring device in which one end of the wire is connected to the armature and the other ring is connected to the remaining end of wire.Armature is basically a piece of an electrical machine that is used to carry the electrical current.

Conclusion:

Hence, agenerator is made up of the parts like a permanent magnet, a set of brushes, an armature which is made of wire loops and a slip ring device that is used for the connection of circuit.
