Generator

Generator means generating electricity.

Generators are a device which turns motive power (mechanical energy) into electricity either alternating current (A.C.) or direct current (D.C.).

Generators generate electricity

A useful mnemonic device to remember this is:

Unlike

GEnErators produce
ElEctricity

Unlike

Motors produce
Movement

Or more accurately

Motors produce
Mechanical power

There are two main ways to generate electricity

  1. Moving a wire in a magnetic field
  2. Moving a magnet in a coil of wire

 

To increase the voltage or current generated

  1. Spin the coil faster
  2. Put more turns on the armature (coil)
  3. Use a stronger magnet
