What will be the impact of reduced voltage applied to an AC induction motor during the starting period?

Correct Answer: Option D — decrease the starting current and decrease the starting torque

Torque in an induction motor is proportional to the square of the applied voltage. Reducing the voltage during startup decreases the starting current, which protects the distribution system, but simultaneously results in a significant reduction in starting torque, potentially preventing the motor from reaching full operating speed.
