A neon lamp is an example of a gas-discharge lamp, useful both for illumination and as a voltage regulator. A flashtube generates a short pulse of intense light useful for photography by sending a heavy current through a gas arc discharge. Corona discharges are used in photocopiers.
A discharge is a type of sentence imposed by a court whereby no punishment is imposed. An absolute discharge is an unconditional discharge whereby the court finds that a crime has technically been committed but that any punishment of the defendant would be inappropriate and the case is closed. In some jurisdictions, an absolute discharge means ...
A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure.
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.
Electrostatic discharge (ESD) phenomena vary in complexity and magnitude, with the electric spark being the most visible and dramatic example. This occurs when a strong electric field ionizes the air, creating a conductive channel that can convey an electric current.
A dishonorable discharge (DD) is a punitive discharge that can only be handed down at a general court-martial after conviction(s) of serious offenses (e.g., felony-like crimes such as desertion before an enemy, drug distribution, sexual assault, murder, etc.) by a military judge or panel (jury).
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.
Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionization of the gas. Depending on several factors, the discharge may radiate visible light. Depending on several factors, the discharge may radiate visible light.
