List of electrical phenomena

This is a list of electrical phenomena. Electrical phenomena are a somewhat arbitrary division of 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 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 polarization — Orientation of charges in certain 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 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 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 &mdash; Plasma occur when gas is heated to very high temperatures and it disassociates into positive and negative charges.
 * 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 states 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.
 * Sparks &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 currents &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 tubes.
 * 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.
 * Whistlers &mdash; Very low frequency radio wave generated by lightning.
