Q. The main objective of drawing root locus plot is :
  • (A) to obtain a clear picture about the open loop poles and zeroes of the system
  • (B) to obtain a clear picture about the transient response of feedback system for various values of open loop gain k
  • (C) to determine sufficient condition for the value of ‘k’ that will make the feedback system unstable
  • (D) both b and c
💬 Discuss
✅ Correct Answer: (D) both b and c

Explanation: the main objective of drawing root locus plot is to obtain a clear picture about the transient response of feedback system for various values of open loop gain k and to determine sufficient condition for the value of ‘k’ that will make the feedback system unstable.
