Solution
The Nyquist plot is a graphical representation used to assess the stability of a control system in the frequency domain by analyzing the encirclements of the critical point.
Correct Answer:
B
— It helps in determining the stability of a system in the frequency domain.
Q. What is the significance of the time constant in a first-order system?
A.
It determines the system's stability.
B.
It indicates how quickly the system responds to changes.
C.
It is irrelevant to system performance.
D.
It defines the system's frequency response.
Solution
The time constant in a first-order system indicates how quickly the system responds to changes in input, with a smaller time constant indicating a faster response.

B
— It indicates how quickly the system responds to changes.
Q. What is the Thevenin equivalent voltage (Vth) across terminals A and B in a circuit with a 10V source and a 2Ω resistor in series with a 4Ω resistor?
A.
10V
B.
7.5V
C.
5V
D.
2.5V
Solution
Thevenin voltage is calculated using voltage division: Vth = 10V * (4Ω / (2Ω + 4Ω)) = 10V * (4/6) = 6.67V.
