Electric arc - Wikipedia 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 characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc.[email protected]
