Electrical Engineering XYZ MCQs

An induction motor is, in general analogous to:

1. Auto transformer
2. Two winding transformer with secondary open circuited
3. Two winding transformer with secondary short circuited
4. None of the above

Correct answer: 3. Two winding transformer with secondary short circuited

Explanation: An induction motor can be analogously compared to a two-winding transformer, where the primary winding is analogous to the stator and the secondary winding to the rotor. When the rotor is short-circuited (as it is made of closed-loop conductors or bars), it is similar to the secondary of a transformer being short-circuited. This analogy is used to analyze the behavior of induction motors under various operating conditions, applying transformer principles like mutual induction and impedance transformation.
