Correct AnswerC. Low resistance and high inductance
Quick Explanation
In a split-phase motor, the running winding is designed with relatively low resistance and high inductive reactance, while the auxiliary starting winding has higher resistance and lower reactance to create phase displacement between currents. Therefore option C.
Detailed Explanation
Correct Answer
C — Low resistance and high inductance
Concept and Reasoning
In a split-phase motor, the running winding is designed with relatively low resistance and high inductive reactance, while the auxiliary starting winding has higher resistance and lower reactance to create phase displacement between currents. Therefore option C.
Calculation / Key Relation
Running winding: low R, high X
auxiliary: high R, low X
Exam Takeaway
Phase splitting is produced by different R/X ratios.
Common Mistake
Do not reverse the resistance characteristics of running and starting windings.
