Web10th Feb, 2015. Nageswara Rao Posinasetti. University of Northern Iowa. An arc is generated between two conductors of electricity, cathode and anode (considering direct current, DC), when they are ... 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 visible light. An arc discharge is initiated either by thermionic emission or by field … See more 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. … 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 … See more Exposure to an arc-producing device can pose health hazards. An arc formed in air will ionize oxygen and nitrogen, which then can re-form into reactive molecules such as 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 … 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 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 See more • Arc transmitter • List of light sources • Marx generator • Spark gap See more
