Reason (R): Lead compensation achieves the desired result through the merits of its phase lead contribution.
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 true
Answer:A
Reason (R): Lead compensation achieves the desired result through the merits of its phase lead contribution.
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 true
Explanation: A lead compensator provides a better gain margin by introducing a positive shift in the phase plot and thus increasing the phase crossover frequency. Thus the system becomes comparatively more stable by using a lead compensator.
