*1 a : a [[fundamental]] [[form]] of [[energy]] [[observable]] in positive and negative [[forms]] that occurs [[naturally]] (as in lightning) or is produced (as in a generator) and that is [[expressed]] in terms of the [[Motion|movement]] and [[interaction]] of [[electrons]]

==Description==
'''Electricity''' (from the New Latin ēlectricus, "amber-like"[a]) is a general term that [[encompasses]] a variety of [[phenomena]] resulting from the [[presence]] and [[flow]] of [http://en.wikipedia.org/wiki/Electric_charge electric charge]. These include many easily recognizable [[phenomena]], such as [http://en.wikipedia.org/wiki/Lightning lightning] and [http://en.wikipedia.org/wiki/Static_electricity static electricity], but in addition, less familiar [[concepts]], such as the [http://en.wikipedia.org/wiki/Electromagnetic_field electromagnetic field] and [http://en.wikipedia.org/wiki/Electromagnetic_induction electromagnetic induction].
In general usage, the word "electricity" is adequate to refer to a [[number]] of [[physical]] [[effects]]. In scientific usage, however, the term is vague, and these related, but distinct, [[concepts]] are better identified by more precise terms:
* [http://en.wikipedia.org/wiki/Electric_charge Electric charge] – a property of some subatomic [[particles]], which determines their electromagnetic [[interactions]]. Electrically charged [[matter]] is [[influenced]] by, and produces, [http://en.wikipedia.org/wiki/Electromagnetic_field electromagnetic fields].
* [http://en.wikipedia.org/wiki/Electric_current Electric current] – a movement or [[flow]] of electrically charged [[particles]], typically measured in [http://en.wikipedia.org/wiki/Ampere amperes].
* [http://en.wikipedia.org/wiki/Electric_field Electric field] – an [[influence]] produced by an [http://en.wikipedia.org/wiki/Electric_charge electric charge] on other charges in its vicinity.
* [http://en.wikipedia.org/wiki/Electric_potential Electric potential] – the [[capacity]] of an [http://en.wikipedia.org/wiki/Electric_field electric field] to do [[work]] on an [http://en.wikipedia.org/wiki/Electric_charge electric charge], typically measured in [http://en.wikipedia.org/wiki/Volt volts].
* [http://en.wikipedia.org/wiki/Electromagnetism Electromagnetism] – a fundamental [[interaction]] between the [[magnetic]] field and the [[presence]] and [[motion]] of an [http://en.wikipedia.org/wiki/Electric_charge electric charge].
Electrical [[phenomena]] have been [[studied]] since antiquity, though advances in the [[science]] were not made until the [http://www.wikipedia.org/wiki/17th_Century seventeenth] and [http://www.wikipedia.org/wiki/18th_Century eighteenth centuries]. Practical [[applications]] for electricity however remained few, and it would not be until the late [http://www.wikipedia.org/wiki/19th_Century nineteenth century] that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary [[versatility]] as a [[source]] of [[energy]] means it can be put to an almost limitless set of [[applications]] which include transport, heating, lighting, [[communications]], and [[computation]]. The backbone of modern industrial [[society]] is, and for the foreseeable [[future]] can be expected to remain, the use of electrical [[power]].[http://en.wikipedia.org/wiki/Electricity]
