Question

Assertion (A): In a shunt regulator, the control element is connected in shunt with the load to achieve constant output voltage.

Reason (R): The impedance of the control element varies to keep the total current flowing through the load and the control element constant.

(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

I had been asked this question in a job interview.

This question is from State Models for Linear Continuous-Time Systems in portion State Variable Analysis and Design of Control Systems

Answer 1

Right choice is (c) A is True and R is false

For explanation I would say: Shunt regulator refers to the winding connected in shunt or parallel and to achieve constant output voltage.
