Question 562Electricity & Electronics - Assistant Engineer

The correct answer is A) by applying torque in the opposite direction of rotation direction, the motor briefly regenerates power back into the mains, which rapidly slows down the motor. This is correct because during regenerative braking, when the motor is driven in the opposite direction of its current rotation, it generates electrical power that is fed back into the main power supply. This regenerative power dissipation in the opposite direction causes the motor to rapidly slow down. The other options are incorrect because applying torque in the same direction of rotation would accelerate the motor, not slow it down, and regenerating power back into the mains would not speed up the motor.
