A 230V-d. c shunt motor runs at 800r. p.m. and takes
armature current of 50A. Find the resistance to be added
to the field circuit to increase speed to 1000r. p.m. at an
armature current of 80A. Assume flux proportional to
field current. Armature resistance 0.15ohms and field
winding resistance = 250ohms
