Two separately excited DC generators are connected in parallel to supply a total load of 300 A. The two generators have the following parameters: G1: R. = 0.25N and induced E.M.F=220 V G2: Ra = 0.3 N and induced E.M.F=250 V Find Mathematically: (i) The armature current of each generator, The bus-bar voltage, (ii) The power sharing by each generator, (iii) Repeat (i) and (ii) if the load current decreases to 100A.
