Electricity

How is it made?

What is Electricity?

• The flow of electrons in usually in metals

• Metals are good electrical conductors because of the way the share electrons, there are “Free electrons” that can move through out the metal.

Electromagnetism

• If you run electricity through a wire

you will generate a magnetic field

• If you move a magnet near a wire, you will generate an electric current

Generators

• This generator is spinning a coil of wire inside of a magnet

• This generator moves a magnet near a coil of copper wire to generate a current

Power Plants

• Most power plants burn something

• to generate steam

• which is used to turn a turbine

• Which generates electricity

A motor is a generator

• You can either use electricity to run a motor….

• Just depends on what is driving it…
