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.
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 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.
IEC 61000-4-2 is the International Electrotechnical Commission's immunity standard on electrostatic discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. [1]
