| electricity |
A form of energy that comes from the movement of electrons and protons. It can be produced by friction (as by rubbing wax with wool), by chemical action (as in a storage battery) or by induction (as in a dynamo ?an electric motor or generator). Electricity is used to produce light, heat, power, etc. Electricity moving in a stream, as through a wire, is called electric current.
