Electric Arc - Electrical Conduction In Gases, Properties Of The Arc, Uses Of Electric Arcs


An electric arc is a high-current, low-voltage electrical discharge between electrodes in the presence of gases. In an electric arc, electrons are emitted from a heated cathode. Arcs can be formed in high, atmospheric, or low pressures, and in various gases. They have wide uses as highly luminous lamps, as furnaces for heating, cutting and welding, and as tools for spectrochemical analysis.
