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 emission. After initiation, the arc relies on thermionic emission of electrons from the electrodes supporting … WebThe degree of dissociation of oxygen has been measured in the positive column plasma of a glow discharge by two different methods (the ozone method and the Wrede-Harteck …
