In electromagnetism, an electric discharge is the release and transmission of electricity in an applied electric field through a medium such as a gas (i.e., an outgoing flow of electric current through a non-metal medium).
The I-K region is a region of arc discharge; the plasma is concentrated in a narrow channel along the center of the tube; a great amount of radiation is produced. In cold cathode tubes, the electric discharge in gas has three regions, with distinct current–voltage characteristics: [1] I: Townsend discharge, below the breakdown voltage. At low ...
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.
Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length.
The discharge requires a source of free electrons and a significant electric field; without both, the phenomenon does not occur. The Townsend discharge is named after John Sealy Townsend, who discovered the fundamental ionisation mechanism by his work circa 1897 at the Cavendish Laboratory, Cambridge.
Nigerian Electricity Regulatory Commission (NERC) is an independent regulatory body with authority for the regulation of the electric power industry in Nigeria. NERC was formed in 2005 under the Obasanjo administration’s economic reform agenda through the Electric Power Sector Reform Act, 2005 for formation and review of electricity tariffs, transparent policies regarding subsidies ...
A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
Electricity generation in Nigeria began in Lagos in 1886 with the use of generators to provide 60 kW. [10] In 1923, tin miners installed a 2 MW plant on the Kwali River; six years later, the Nigerian Electricity Supply Company, a private firm, was established near Jos to manage a hydroelectric plant at Kura to power the mining industry.
