A 220 volts dc series motor runs at 800 rpm when taking a
current of 15 amperes. The motor has an armature resistance of 0.3
ohms and series field resistance of 0.2 ohms. Find the resistance
to be connected in series with the armature if it has to take the
same current at the same voltage, at 600 rpm.
