A 3 phase 50hz star connected motor has rotor resistance and stand still reactance of 0.025ohm and 0.35 ohm respectively. The full load slip is 5% calculate the resistance per phase of a star connected rheostat which when connected to rotor will give a pull out torque at one half of the full load speed what is then the power factor?
