Electrical Machines A separately-excited DC generator, running at rated speed, has 6 volts across its armature terminals with no field current. When field winding is excited with one ampere, the voltage builds up to 250 V at no load. In case field current is reduced to zero, with the speed remaining unaltered, the armature terminal voltage would be 6 V less than 6 V zero more than 6 V 6 V less than 6 V zero more than 6 V ANSWER DOWNLOAD EXAMIANS APP
