Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
The starting torque of a resistance-start induction motor is typically 1.5 to 2 times the full-load torque.
Therefore, the closest option to the actual value is: (2) 1.5
It's important to note that the exact starting torque can vary depending on factors like the specific motor design, starting circuit conditions, and load characteristics.
1) 4.5: This is too high for a resistance-start motor. Typically, higher starting torques are achieved with methods like capacitor-start or autotransformer starting.
3) 9.5: This is significantly higher than the typical range for resistance-start motors and is more likely to be seen in other starting methods or high-performance motors.
4) 7.5: This falls within the possible range for resistance-start motors, but it's generally on the higher end.
