An air-cooled AC induction motor is initially operating at steady-state conditions, producing a work output of 50 hp.
A reduction in cooling air flow rate to the motor causes the average stator winding temperature to increase by 20ºF.
To maintain a 50 hp work output at the higher stator winding temperature, the voltage applied to the motor must be __________ because the stator winding resistance has __________.
A. increased; increased
B. increased; decreased
C. decreased; increased
D. decreased; decreased
