NODON: ELECTROLYTIC RECTIFIERS. 525 f = alternating = 119 ^= of rectified current = 102 alternating current strength before entering valves = 10amperes. /= strength of current in battery = amperes. The efficiency is then practically the same as with continuouscurrents. The storage battery can further be used as a derived current is taken from the terminals of the battery whileit is charged with a single valve. A consideration of the resultsleads to the conclusion that with a battery of low capacity and withas low an internal resistance as possible, a practically continuousdischarge current may be obtained. Rectification of Polyphase Currents. Two-phase or three-phase currents can be rectified by meansof the valves. By an arr
