Electricity

    Electricity is one of the basic forms of energy. Electricity is associated with electric charge, a property ofcertain elementary particles such as electrons and protons; two of the basic particles that make up the atoms of all ordinary matter. Electric charges can be stationary as in static electricity, or moving as in an electric current.

    Electrical activity takes place constantly everywhere in the universe. 'Electrical forces hold molecules together. The nervous systems of animals work by means of weak electric signals transmitted between neurons (nerve celis). Electricity is generated, transmitted, and converted into heat, light, motion, and other forms of Energy through natural processes, as well as by devices built by people.

     Electricity is an extremely versatile form of energy. It can be generated in many' ways and from many different sources, it can be sent almost instaneously over long distances. Electricity can also be converted efficiently in to other forms of energy, and it can be stored. Because of this versatility, electricity plays a part in nearly every aspect of modern technology. Electricity provides light, heat, and mechanical power. It makes telephones, computers, televisions, and countless other necessities and luxuries possible.
