Q. Plugging is applied in a motor, if we don’t make the switch OFF what will happen?
✅ Correct Answer: (B)
motor will come to rest and will start rotating in another direction
Explanation: if the switch is kept on near to zero speed, motor will have braking torque acting in opposite direction greater than the electromechanical torque. thus, motor will come to rest and for the next instant motor will start rotating in opposite direction.
