Electrical Engineering XYZ MCQs
In circle diagram for induction motor, diameter of circle represents which of the following:
- Running torque
- Line voltage
- Slip
- Rotor current
Correct answer: 4. Rotor Current
Explanation: The diameter of this circle, extending from one edge to the other through the center, symbolically represents the maximum value of the rotor current that can occur under any load condition. Specifically, the rotor current is maximum when the motor is at standstill (i.e., when the slip, s = 1).
