Editing List of electrical phenomena (section)

{{Short description|Phenomena involving electrical occurrences}}
This is a list of [[electrical]] phenomena. Electrical phenomena are a somewhat arbitrary division of [[electromagnetic phenomenon|electromagnetic phenomena]].

Some examples are:

*[[Atmospheric electricity]]
*[[Biefeld–Brown effect]] &mdash; Thought by the person who coined the name, [[Thomas Townsend Brown]], to be an [[anti-gravity]] effect, it is generally attributed to [[electrohydrodynamics]] (EHD) or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics.
*[[Bioelectrogenesis]] &mdash; The generation of electricity by living organisms.
*[[Capacitive coupling]] — Transfer of energy within an [[electrical network]] or between distant networks by means of [[displacement current]].
*[[Contact electrification]] &mdash; The phenomenon of electrification by contact. When two objects were touched together, sometimes the objects became spontaneously charged (οne negative charge, one positive charge).
*[[Corona discharge|Corona effect]] — Build-up of charges in a high-voltage conductor (common in AC transmission lines), which ionizes the air and produces visible [[light]], usually purple.
*[[Dielectric|Dielectric polarization]] — Orientation of charges in certain [[Insulator (electricity)|insulators]] inside an external static [[electric field]], such as when a charged object is brought close, which produces an electric field inside the insulator.
*[[Direct Current]]  &mdash; (old: Galvanic Current)  or "continuous current"; The continuous flow of electricity through a conductor such as a wire from high to low potential.
*[[Electromagnetic induction]] &mdash; Production of a voltage by a time-varying magnetic flux.
*[[Electroluminescence]] &mdash; The phenomenon wherein a material emits light in response to an electric current passed through it, or to a strong electric field.
*[[Electrostatic induction]] — Redistribution of charges in a conductor inside an external static electric field, such as when a charged object is brought close.
*[[Electrical conduction]] &mdash; The movement of electrically charged particles through transmission medium.
*[[Electric shock]] &mdash; Physiological reaction of a biological organism to the passage of electric current through its body.
*[[Ferranti effect]] — A rise in the amplitude of the AC voltage at the receiving end of a [[transmission line]], compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open-circuited.
*[[Ferroelectric effect]] &mdash; The phenomenon whereby certain ionic crystals may exhibit a spontaneous dipole moment.
*[[Hall effect]] — Separation of charges in a current-carrying conductor inside an external magnetic field, which produces a voltage across the conductor.
*[[Inductance]]  &mdash;  The phenomenon whereby the property of a circuit by which energy is stored in the form of an electromagnetic field.
*[[Induction heating]] — Heat produced in a conductor when [[Eddy current|eddy currents]] pass through it.
*[[Joule heating]] — Heat produced in a conductor when charges move through it, such as in resistors and wires.
*[[Lightning]] &mdash;  powerful natural electrostatic discharge produced during a thunderstorm. Lightning's abrupt electric discharge is accompanied by the emission of light.
*[[Noise (electronics)|Noise]] and [[electromagnetic interference]] — Unwanted and usually random disturbance in an electrical signal. A [[Faraday cage]] can be used to attenuate electromagnetic fields, even to avoid the discharge from a [[Tesla coil]].
*[[Photoconductivity]] &mdash;  The phenomenon in which a material becomes more conductive due to the absorption of electro-magnetic radiation such as visible light, ultraviolet light, or gamma radiation.
*[[Photoelectric effect]] &mdash;  Emission of electrons from a surface (usually metallic) upon exposure to, and absorption of, electromagnetic radiation (such as visible light and ultraviolet radiation).
*[[Photovoltaic effect]] &mdash; Production of a voltage by light exposure.
*[[Piezoelectric effect]] &mdash; Ability of certain crystals to generate a voltage in response to applied mechanical stress.
*[[Plasma (physics)|Plasma]] &mdash; Plasma occur when gas is heated to very high temperatures and it disassociates into positive and negative charges.
*[[Proximity effect (electromagnetism)|Proximity effect]] — Redistribution of charge flow in a conductor carrying alternating current when there are other nearby current-carrying conductors.
*[[Pyroelectric effect]] &mdash; The potential created in certain materials when they are heated.
*[[Redox]]  &mdash; (short for ''reduction-oxidation'' reaction) A [[chemical reaction]] in which the [[oxidation state]]s of atoms are changed. 
*[[Skin effect]] — Tendency of charges to distribute at the surface of a conductor, when an alternating current passes through it.
*[[Static electricity]]  &mdash;  Class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltages of sufficient magnitude to produce visible attraction (e.g., static cling), repulsion, and sparks.
*[[Electric spark|Spark]]s  &mdash; Electrical breakdown of a medium that produces an ongoing plasma discharge, similar to the instant spark, resulting from a current flowing through normally nonconductive media such as air.
*[[Telluric current]]s &mdash; Extremely low frequency electric current that occurs naturally over large underground areas at or near the surface of the Earth. 
*[[Thermionic emission]] &mdash; the emission of electrons from a heated electrode, usually the cathode, the principle underlying most [[vacuum tube]]s.
*[[Thermoelectric effect]] &mdash; the [[Seebeck effect]], the [[Peltier effect]], and the [[Thomson effect]].
*[[Thunderstorm]] &mdash; also  electrical storm, form of weather characterized by the presence of [[lightning]] and its acoustic effect on the Earth's atmosphere known as [[thunder]].
*[[Triboelectric effect]] &mdash; Type of contact electrification in which objects become electrically charged after coming into contact and are then separated. A [[Van de Graaff generator]] is based on this principle.
*[[Whistler (radio)|Whistlers]]<ref>{{Cite web |url=http://www.altair.org/natradio.htm |title=Altair's site on Natural Radio Signals |access-date=2003-01-23 |archive-url=https://web.archive.org/web/20030207044129/http://www.altair.org/natradio.htm |archive-date=2003-02-07 |url-status=dead }}</ref> &mdash; Very low frequency radio wave generated by lightning.
