ts will be obtained on the direct-current side. As electrolytes, ammonium phosphate or sodium phosphateare considered best. The cell should be artificially cooled to worksatisfactorily. The voltage may be regulated by means of resistancein either the alternating-current or the direct-current… … Fig. 2.»1; Mercury-Vapor Arc Rectifiers pHcity. On account of its small direct-current output, its poorefficiency, and comparatively high cost of maintenance, it is not asyet of great commercial importance. Mercury=Vapor Arc Rectifier.
