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).
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.
An electrical component that stores energy in an electric field. capacitor-input filter A power supply network where a capacitor is the first element following the rectifier. capacitor voltage transformer In electrical power systems, an instrument transformer for measuring voltage that uses a capacitive voltage divider. capacity factor
Transition from glow to arc discharge in argon, by increasing the gas pressure. Voltage-current characteristics of electrical discharge in neon at 1 torr, with two planar electrodes separated by 50 cm. [dubious – discuss] A: random pulses by cosmic radiation B: saturation current C: avalanche Townsend discharge D: self-sustained Townsend ...
This is a list of materials ordered by how they develop a charge relative to other materials on the list. Johan Carl Wilcke published the first one in a 1757 paper. [ 24 ] [ 25 ] The series was expanded by Shaw [ 1 ] and Henniker [ 71 ] by including natural and synthetic polymers, and included alterations in the sequence depending on surface ...
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.
Electrical discharge machining (or EDM) is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. A machining method typically used for hard metals, EDM makes it possible to work with metals for which traditional machining techniques are ineffective.
The International Electrotechnical Commission (IEC; French: Commission électrotechnique internationale) is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies.
