voltaicity is a command term encompassing a variety of phenomena resulting from the presence and emanate of electrical charge. These include galore(postnominal) easily recognizable phenomena, such as lightning, static electrical energy, and the flow of electrical latest in an electrical wire. In addition, electricity encompasses less familiar concepts such as the electro magnetized correction and electromagnetic induction.
The word is from the New Latin ?lectricus, amber-like[a], coined in the course of study 1600 from the Greek ???????? (electron) meaning amber (hardened plant resin), because static electricity effects were produced classically by rubbing amber.
Usage
In general usage, the word electricity adequately refers to a number of physiological effects. In scientific usage, however, the term is vague, and these related, but distinct, concepts are let out identified by more precise terms:
* Electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically aerated matter is god by, and produces, electromagnetic fields.
* Electric current: a movement or flow of electrically charged particles, typically measured in amperes.
* Electric field: an influence produced by an electric charge on other charges in its vicinity.
* Electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts.
* Electromagnetism: a fundamental interaction between the magnetic field and the presence and motion of an electric charge.
The most gross use of the word electricity is less precise. It refers to:
* Electric reason provided commercially by the electrical power industry. In a loose but common use of the term, electricity may be used to mean wired for electricity which gist a working connection to an electric power station. such(prenominal) a connection grants the user of electricity access to the electric field present in electrical wiring, and thus to electric power.
