If the excitation is increased both power angle and power factor decrease both power angle and power factor increase power angle increase and power factor decrease power angle decrease and power factor increase both power angle and power factor decrease both power angle and power factor increase power angle increase and power factor decrease power angle decrease and power factor increase ANSWER DOWNLOAD EXAMIANS APP
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 zero 6 V more than 6 V less than 6 V zero 6 V more than 6 V less than 6 V ANSWER DOWNLOAD EXAMIANS APP
