21. The three factors which cause decrease in the terminal voltage of a shunt generator are (a) armature reactances (b) armature resistance armature leakages (d) armature reaction (e) reduction in field current 22. If field resistance of a d.c. shunt generator is increased beyond its critical value, the generator (a) output voltage will exceed its name-plate rating (b) will not build up (c) may burn out if loaded to its name-plate rating (d ) power output may exceed its name-plate Rating
