If R  decreases to 5  , the total field resistance becomes 29  , and the terminal voltage line gets
                      adj
                 shallower.  The new point where the distance  between  the  E  A  and  V T   curves is exactly 4.5 V
                 corresponds to a terminal voltage of 125 V, as shown below.



































                 Note that decreasing the field resistance of the shunt generator increases the terminal voltage.

          8-27.  A 120-V 50-A cumulatively compounded dc generator has the following characteristics:
                                R   A  R   S  021.               N  1000 turns
