Question

Assertion (A): The stator winding of a control transformer has higher impedance per phase

Reason (R): The rotor of control transformer is cylindrical in shape.

(a) Both A and R are true and R is correct explanation of A

(b) Both A and R are true and R is not correct Explanation of A

(c) A is True and R is false

(d) A is False and R is true

This question was addressed to me in quiz.

I'm obligated to ask this question of State Models for Linear Continuous-Time Systems in chapter State Variable Analysis and Design of Control Systems

Answer 1

The correct choice is (b) Both A and R are true and R is not correct Explanation of A

To explain: The control transformer has two parts as stator which is stationary having higher impedance and rotor which was rotatory was cylindrical in shape.
