Question

Two shunt generators work in parallel. Each has an armature resistance of 0.015Ω and a shunt-field resistance of 85Ω . Machine A is excited so that its e.m.f. is 600V, while the other machine B is excited so that its e.m.f. is 620V. What is the output of each machine when they jointly supply a load of 2500A and what is the busbar voltage?
