Experimental study: - low current (2 - 5 A): Ag, Cu, W. - high current (100 - 2000 A): AgNi, AgWC, AgCdO, AgZnO, AgSnO2.; A macroscopic model based on Mackeown's (for the electric field) and Murphy's theories (for electron current density) is used to

The power lost by conduction into copper, silver and tungsten cathodes surrounded by water-cooled brass was determined experimentally. The measurements were made for prolonged short arcs (0.4-1 mm) at low current (2.6-5 A) in argon at 1 atm. The expe
