Electricity is a phenomenon that is a result of the existence of electrical charge ("What is Electricity? ┬Ł pg.1).
Electricity is one of the most important forms of energy. Electricity produces light and heat, and it provides power for household appliances and industrial machinery. Electric power also enables us to have telephones, computers, motion pictures, television and radio (World Book).

The negative charge of the electron is equa
