Assertion (A): The pull-in winding carries current throughout cranking.

Reason (R): The pull-in winding is connected across the main solenoid contacts.

Select the correct answer from the options below.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: A

The reason is correct and it is precisely why the assertion is false: once the contacts close, both ends of the winding are at the same potential and no current flows. That saves a considerable current during cranking. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. The shared behaviour explains why these belong together and the differences explain why both exist. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb.
