Basics of Generator Principles

Click on the flashcard to see the answer



What is the basic principle behind electrical generators?

The basic principle behind electrical generators is electromagnetic induction, where a conductor moving through a magnetic field induces an electric current.

What components are essential in an electrical generator?

The essential components of an electrical generator include the stator, rotor, armature, field winding, and slip rings (in AC generators).

How does a generator convert mechanical energy into electrical energy?

A generator converts mechanical energy into electrical energy through the movement of a conductor within a magnetic field, inducing current via electromagnetic induction.

What is the role of the rotor in a generator?

The rotor is the rotating component of a generator that creates relative motion with respect to the magnetic field, facilitating electromagnetic induction.

What are slip rings used for in AC generators?

Slip rings are used to provide continuous electrical connection between the rotating coil and outer circuit while allowing free rotation of the coil.
