se the armature A to be raised and thecircuit at E is closed. The main current now passes Arc Lamps 203 from P, through R, to the armature A, point E, andto the negative terminal N. Thus the current isshunted around the lamp and all other lamps in thecircuit are left burning as before. The purpose… … Figure 136 With arc lamps for use on series circuits it is essen-tial for the successful operation of the lamp that botha shunt and series coil be provided. For lamps to beused on multiple circuits, or circuits where the voltageis constant, and where the current flow depends onlyon the resistance,…
