Two generators, each having no-load voltage of 500 V, are

Two generators, each having no-load voltage of 500 V, are connected in parallel to a constant resistance load consuming 400 kW. The terminal potential difference of one machine falls linearly to 470 V as the load is increased to 850 A while that of the other falls linearly to 460 V when the load is 600 A. Find the load current and voltage of each generator. If the induced e.m.f. of one machine is increased to share load equally, find the new current and voltage.
