The correct answer is B) relatively high starting torque and low stator current. In a wound-rotor induction motor, inserting a high resistance in series with the rotor winding at startup increases the rotor resistance, which in turn increases the starting torque of the motor. This is because the high rotor resistance limits the rotor current, resulting in a stronger magnetic field interaction between the stator and rotor, thereby producing a higher starting torque. The high starting torque is achieved with a relatively low stator current, as the high rotor resistance limits the overall current drawn from the power source. This makes option B the correct answer, as it accurately describes the characteristic of a wound-rotor induction motor with a high resistance inserted in the rotor circuit during startup. The other options are incorrect because they do not correctly describe the relationship between the starting torque and stator current in this type of motor configuration.
