8) The speed of rotor of an induction-motor is :

the same as the synchronous speed

higher than the synchronous speed

lesser than the synchronous speed

determined by the frequency and the number of poles

Answer is:

lesser than the synchronous speed

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:

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:
