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 become zero increase remain the same decrease become zero increase remain the same decrease ANSWER DOWNLOAD EXAMIANS APP
