1. a 300 v, de shunt motor is taking 50 a. resistance of the shunt field and the armature
are 150 ohms and 0.03 ohms respectively. motor is running with a speed of 1000 rpm.
if now an additional resistance of 0.25 ohms is added in series with the armature.
calculate the new value of speed. assume load constant
