l circuit are in parallel. If for such a machine the resistance in the external circuitfalls, thus causing the machine for a given voltage to give anincreased current, a smaller fraction of that greater currentcirculates round the field coils; thus the strength of the fielddoes not necessarily… … The rise or fall in voltage depends on the relation betweenthe various resistances which will determine whether the riseproduced in the current in thefield coils is greater or less thanthe fall due to the fact that asmaller fraction of that currentcirculates through them. In a compound machine,…
