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.
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.
Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.

Views of a liquid crystal display, both with electroluminescent backlight switched on (top) and switched off (bottom). Electroluminescence (EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field.
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 ...
A facility that changes electric power into some form that can be stored and usefully reconverted back to electric power, for example, pumped storage or battery systems. power supply A subsystem of a computer or other electronic device that turns electric power from a wall plug or batteries into a form suitable for use by the system.
The list is full of examples of this art style and movement that were created by artists from all around the world. So, check them out; maybe it will convince you to become a surrealism enthusiast.
