Comparison of brush discharge (left) and corona discharges (right) from a Tesla coil Closeup of a Tesla coil brush discharge, showing its filamentous nature. A brush discharge is an electrical disruptive discharge similar to a corona discharge that takes place at an electrode with a high voltage applied to it, embedded in a nonconducting fluid ...
Cone discharge, also called bulking brush discharge, occurs over surfaces of charged powders with resistance above 10 10 ohms, or also deep through the powder mass. Cone discharges are not usually observed in dust volumes below 1 m 3. The energy involved depends on the grain size of the powder and the charge magnitude, and can reach up to 20 mJ.
A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air.
Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.

Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.
