Electrical phenomena are commonplace and unusual events that can be observed and that illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary division of electromagnetic phenomena. Some examples are
Biefeld–Brown effect — Thought by the person who coined the name, Thomas Townsend Brown, to be an anti-gravity effect, it is generally attributed to electrohydrodynamics or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics.
Bioelectrogenesis — The generation of electricity by living organisms.
Contact electrification — The phenomenon of electrification by contact. When two objects were touched together, sometimes the objects became spontaneously charged.
Direct Current — or "continuous current"; The continuous flow of electricity through a conductor such as a wire from high to low potential.
Electroluminescence — The phenomenon wherein a material emits light in response to an electric current passed through it, or to a strong electric field.
Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body.
Ferroelectric effect — The phenomenon whereby certain ionic crystals may exhibit a spontaneous dipole moment.
Inductance — The phenomenon whereby the property of a circuit by which energy is stored in the form of an electromagnetic field.
Lightning — powerful natural electrostatic discharge produced during a thunderstorm. Lightning's abrupt electric discharge is accompanied by the emission of light.
Photoelectric effect — Emission of electrons from a surface upon exposure to, and absorption of, electromagnetic radiation.
Piezoelectric effect — Ability of certain crystals to generate a voltage in response to applied mechanical stress.
Plasma — Plasma occur when gas is heated to very high temperatures and it disassociates into positive and negative charges.
Pyroelectric effect — The potential created in certain materials when they are heated.
Redox — A chemical reaction in which the oxidation states of atoms are changed.
Static electricity — Class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltages of sufficient magnitude to produce visible attraction, repulsion, and sparks.
Sparks — 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.
