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:
Or more accurately
There are two main ways to generate electricity
- Moving a wire in a magnetic field
- Moving a magnet in a coil of wire
To increase the voltage or current generated
- Spin the coil faster
- Put more turns on the armature (coil)
- Use a stronger magnet
