Electricity
Electricity is the flow of electrical power or charge. Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity, the particle involved is the electron, which carries a charge designated, by convention, as negative. Electricity is a secondary energy source, meaning we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power, and other natural sources, which are called primary sources.
