9) To reverse the direction of rotation of a 3-phase induction-motor, it is necessary to :

interchange all the three line connections

reverse the polarity of the rotor's circuit

increase the resistance of the rotor's circuit

interchange any two out of the three line connections

Answer is:

interchange any two out of the three line connections

slip-rings

rotor windings

stator windings

rotating part

Answer is:

zero starting torque

very small starting torque

very high starting torque

highest starting torque amongst all types of induction motors

Answer is:

limit the starting current

increase the starting current

limit the starting current and to increase the starting torque

decrease the starting torque

Answer is:

It will start after some time

It will continue to run at a lower speed without any damage

It will get heated up and consequently will get damaged

Nothing adverse will happen

Answer is:
