Answer» Right ANSWER is (a) True To explain I would say: If a dc compound machine connected as a generator is run as a motor, the series field connections must be reversed as the ARMATURE CURRENT reverses. The motoring action as cumulative/ differential would then be preserved (same as in the generator). This EQUALLY applies vice VERSA – motor to generator.
