Electrical Machines A dc shunt generator, when driven without any excitation, showed an open circuit voltage of 12 V. When the field winding was excited, the voltage dropped to zero. It happened because there was a break in the armature circuit field resistance was higher than critical resistance there was no residual magnetism in the field circuit field winding was wrongly connected there was a break in the armature circuit field resistance was higher than critical resistance there was no residual magnetism in the field circuit field winding was wrongly connected ANSWER DOWNLOAD EXAMIANS APP
