Show step by step solution and please do not copy the answer from the internet or else i'll downvote.


Extracted text: Two DC shunt generators A and B are rated at a 100 and 150kW at 110V respectively. Their external load characteristics may be considered as straight line. The voltage drop in the terminal voltage from no load to full load is 10V for A and 20V for B. Determine the operating voltage when these generators are operated in parallel to supply a load of 220kW.
