1.	Assertion (A): Feedback compensation is preferred to series compensation.Reason (R): No amplification is required as the energy flows from higher to lower levels.(a) Both assertion and reason are true and R is correct explanation of A(b) Both A and R true but R is not correct explanation of A(c) A is true but R is false(d) A is False but R is trueI had been asked this question in a national level competition.I'm obligated to ask this question of Effect of Adding a Zero to a System in chapter Time Response Analysis, Design Specifications and Performance Indices of Control Systems
Answer» Right OPTION is (a) Both assertion and reason are TRUE and R is correct explanation of A The explanation is: Feedback compensation is preferred to series compensation or CASCADE compensation because: In a feedback compensator energy transfer is from HIGHER to a lower one thereby OBVIATING the need for the feedback amplification.
