Electricity is one of the basic forms of energy. It is associated with electric charge, a property of atomic particles such as electrons and protons. Electric charges can be stationary, as in static electricity, or moving, as in an electric current. Electricity can be generated from many different sources. It can be sent almost instantly over long distances and can also be stored. Moreover, it can be converted efficiently into other forms of energy. Because of this versatility, electricity is an integral part of our modern life.
