electric discharge
Noun: 1. Electrical conduction through a gas in an applied electric field: A flow of electric current through a gaseous medium, such as air, caused by a strong voltage difference. This process often involves the ionization of the gas and can produce visible light, heat, and sound.
- Noun:
- Lightning is a spectacular natural example of an electric discharge between clouds and the ground.
- The neon sign glows due to a controlled electric discharge inside the glass tube.
- Scientists study the properties of plasma created by an electric discharge.
"Dielectric barrier discharge": A type of electric discharge where an insulating layer (dielectric) covers at least one of the electrodes, used in applications like ozone generation and surface treatment.
- The device uses dielectric barrier discharge to clean the air.
"Corona discharge": A localized electric discharge often visible as a faint glow, occurring when a high-voltage conductor ionizes the surrounding air.
- The power lines exhibited a faint corona discharge in the humid weather.
Discharge (verb/noun): The act of releasing or emitting something, such as electricity, a fluid, or an obligation.
- The battery can discharge its energy quickly. (verb)
- The discharge from the factory was monitored for pollutants. (noun)
Electrical discharge machining (EDM): A manufacturing process that uses electric discharges to shape hard metals.
- The intricate part was created using electrical discharge machining.
- Arc: A luminous electrical discharge between two electrodes.
- Spark: A brief, small-scale electric discharge.
- Plasma: An ionized gas state often produced by and synonymous with a sustained electric discharge.
Electric discharge lamp: A lamp that generates light by passing an electric discharge through a gas or vapor.
- Fluorescent lights are a common type of electric discharge lamp.
Partial discharge: A localized electrical discharge that does not completely bridge the gap between conductors, often a sign of insulation degradation.
- Engineers test transformers for signs of partial discharge.
