Slip at maximum torque depends on A rotor resistance and reactance B stator reactance C load current D stator resistance

Stator core loss of squirrel cage induction motor compared to rotor core loss is= A equal B more C less D depends on load

No load test of induction motor is carried out to compute= A stator resistance B rotor resistance C magnetizing reactance D rotor reactance

Short circuit test of induction motor is carried out to compute= A stator resistance B rotor resistance C magnetizing reactance D stator reactance

Auto transformer starter gives the same effect as star/delta strater if its turn ratio = A 0.5 B 0.67 C o.66 D 0.577

Rotor resistance starter is used to obtain= A increased starting torque B decrease starting current C decrease starting loss D increase efficiency

Plugging is a phenomenon to= A braking the motor B to accelerate the motor C to run IM as generator D to start the motor

The slip during plugging operation is given by= A 1-s B 2+s C 1+s D 2-s
