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. Telluric currents — Extremely low frequency electric current that occurs naturally over large underground areas at or near the surface of the Earth.
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.

Modern 3D Lichtenberg figures or "electrical treeing" in a block of clear acrylic, created by irradiating the block with an electron beam.Actual size: 80 mm × 80 mm × 50 mm (3 in × 3 in × 2 in) Lichtenberg figures are generated by a sliding spark discharge on the flask with a mixture of gases.
The study of electrical phenomena dates back to antiquity, with theoretical understanding progressing slowly until the 17th and 18th centuries. The development of the theory of electromagnetism in the 19th century marked significant progress, leading to electricity's industrial and residential application by electrical engineers by the century ...
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 ...
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.
This phenomenon is known as electrostriction, or the reverse piezoelectric effect. This effect enables the element to act as a translating device called an actuator. Piezoelectric materials are used in power actuators, converting electrical energy into mechanical energy, and in acoustic transducers, converting electric fields into sound waves. [2]
