electricity
n.
type of energy which results from the existence of charged particles (used to produce light, heat, etc.)
Electricity
Electricity (from
New Latin ēlectricus, "
amberlike") is a general term for a variety of phenomena resulting from the presence and flow of
electric charge. This includes many well-known
physical phenomena such as
lightning,
electromagnetic fields and
electric currents, and is put to use in
industrial applications such as
electronics and
electric power. These related, but distinct, concepts are better identified by more precise terms:
Electric field — an effect produced by an electrically charged object that exerts a force on other charged objects in its vicinity.
Electric potential — the capacity of an electric field to do work, typically measured in
volts (V).
Electric current — a movement or flow of electrically charged particles, typically measured in
amperes (A).
Electrical energy — the energy made available by the flow of electric charge through an
electrical conductor.
Electric power — the rate at which electric energy is converted to or from another energy form, such as
light,
heat, or
mechanical energy.
Electric charge — a connection conserved property of some
subatomic particles, which determines their
electromagnetic interactions. Electrically charged matter is influenced by, and produces,
electromagnetic fields.
Electromagnetism — a
fundamental interaction

(n.)

(n.)
Fig.: Electrifying energy or characteristic.
(n.)
A power in nature, a manifestation of energy, exhibiting itself when in disturbed equilibrium or in activity by a circuit movement, the fact of direction in which involves polarity, or opposition of properties in opposite directions; also, by attraction for many substances, by a law involving attraction between surfaces of unlike polarity, and repulsion between those of like; by exhibiting accumulated polar tension when the circuit is broken; and by producing heat, light, concussion, and often chemical changes when the circuit passes between the poles or through any imperfectly conducting substance or space. It is generally brought into action by any disturbance of molecular equilibrium, whether from a chemical, physical, or mechanical, cause.
