Explanation
When two DC shunt generators run in parallel with different e.m.f. values, the bus bar voltage settles at a point between the two e.m.f.s, influenced by their internal resistances and load sharing. Considering the armature resistances and given e.m.f. values, the combined bus bar voltage is calculated as 267.5 volts.
