Electric arc - Wikipedia
Sir Humphry Davy discovered the short-pulse electrical arc in 1800. In 1801, he described the phenomenon in a paper published in William Nicholson's Journal of Natural Philosophy, Chemistry and the Arts. According to modern science, Davy's description was a spark rather than an arc. In the same year Davy … See more An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce See more Undesired or unintended electric arcing can have detrimental effects on electric power transmission, distribution systems and electronic equipment. Devices which may cause arcing include switches, circuit breakers, relay contacts, fuses and poor cable terminations. … See more Arc suppression is a method of attempting to reduce or eliminate an electrical arc. There are several possible areas of use of arc suppression methods, among them metal film deposition and sputtering, arc flash protection, electrostatic processes where electrical arcs … See more An electric arc is the form of electric discharge with the highest current density. The maximum current through an arc is limited only by the external circuit, not by the arc itself. See more Industrially, electric arcs are used for welding, plasma cutting, for electrical discharge machining, as an arc lamp in movie projectors, and spotlights in stage lighting.
