In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: An induction motor can, therefore, be made without electrical connections to the rotor. B: Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. C: An induction motor's rotor can be either wound type or squirrel-cage type. D: An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

D: An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. Correct Answer DACB

The correct answer is option 2) i.e. DACB.

Key Points

  • D is the first sentence because it introduces the subject of the passage - 'induction motor'.
  • D mentions 'electric current... needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding'. A mentions that 'An induction motor can, therefore, be made without electrical connections to the rotor'. So, A reinforces the fact that there is no need to electrically connect the rotor to the induction motor. So, A must follow D.
  • C further explains the 'categorization of the rotor', which is talked in A. So, C must follow A.
  • B further explains the 'squirrel-cage induction motors' mentioned in C. So, B must follow C.
