A 200 V, dc series motor takes 20 A when running at 1000 rpm. Calculate the speed at which the motor will run and the current taken from the supply if the field is shunted by a resistance equal to the field resistance and field is reduced to 70% .Assume the load torque remains the same. Armature resistance = 0.502, field resistance = 0.2 2. (3 Marks) A 200 V, dc series motor takes 20 A when running at 1000 rpm.
