Electroluminescence — 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.
The set of physical phenomena associated with electric charges. electrification Applying electric power to a process that was previously done by other means, or, development of an electric power system in a region that previously had none. electroactive polymers A polymer that significantly changes size or shape when exposed to an electric field.
Electrical phenomena are commonplace and unusual events that can be observed which illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary subset of phenomena of electromagnetism in general.
An electrical network consisting of a closed loop, giving a return path for the current. electric current A flow of electric charge through a conductive medium. electric displacement field electric field The region of space surrounding electrically charged particles and time-varying magnetic fields. The electric field represents the force ...
The electric field was formally defined as the force exerted per unit charge, but the concept of potential allows for a more useful and equivalent definition: the electric field is the local gradient of the electric potential. Usually expressed in volts per metre, the vector direction of the field is the line of greatest slope of potential, and ...

The International Electrotechnical Vocabulary (IEV) is managed list of terms and definitions organized by the International Electrotechnical Commission (IEC), which is grouped in classes. It serves to promote the global unification of terminology in the field of electrotechnology, electronics and telecommunications.
