Electrical Machines The magnetic circuit of a dc shunt generator with negligible armature resistance and brush contact voltage drop remains unsaturated when it delivers full-load current at rated terminal voltage. The brushes are kept in the interpolar axis and speed is maintained constant. When the load is switched off, the terminal voltage would decrease remain the same become zero increase decrease remain the same become zero increase ANSWER DOWNLOAD EXAMIANS APP
Electrical Machines When the supply terminal of a DC shunt motor are interchanged The motor will stop. The motor will run much faster in the same direction. The direction of rotation will reverse. The motor will run at its normal speed in the same direction as before. The motor will stop. The motor will run much faster in the same direction. The direction of rotation will reverse. The motor will run at its normal speed in the same direction as before. ANSWER DOWNLOAD EXAMIANS APP
