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