Q1:

Assertion (A): A synchro control transformer has nearly constant impedance across its rotor terminals. Reason (R): Rotor of a synchro control transformer is cylindrical so as to give uniform flux distribution.

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is correct but R is wrong

D R is correct but A is wrong

ANS:A - Both A and R are correct and R is correct explanation of A

The rotor in synchro control transformer is in dumbbell shape not in cylindrical shape.
