In the circle diagram for induction motor, the diameter of the circle represents____________?
Correct answer: B. rotor current
- A. slip
- B. rotor current
- C. running torque
- D. line voltage
Explanation
The induction-motor circle diagram is drawn on a current scale, so its diameter represents the corresponding rotor-current quantity. Slip and torque are obtained from other geometrical relationships in the diagram, not directly from the diameter.
