Electricity

Electricity is the energy that makes everything from toasters to tube trains work.It is also linked with magnetism. Together they form basic forces that holds the universe together- electromagnetism.Electricity starts with atoms and tiny parts of each atom are called electrons.Just as magnets are drawn together,so electrons are drawn to the center of the atom.This attraction is called' electric charge'.Electrons have a ' negative' charge; atomic centers a ' positive' one.It is the combined attraction of billions of tiny electrons to billions of tiny atom centers that creates electricity.
