Question 1

A closed-loop control system is stable if the Nyquist plot of the corresponding open-loop transfer function

Question 2

Consider a circuit shown in figure below:


The circuit is usde for measuring the inductance L1 and resistance R1 of a coil if bridge is balanced when R3 = R4 = 2000 ohms, R2= 1000 ohms R5 = 200 ohms and C =1 μF?

Question 3

The initial contents of a 4-bit shift register is 1011 . The register is shifted six times to the right when input to the register being 101111.

What are the contents of the register after six clock pulses?

Question 4

A generator rated 11 kV, 375 MVA, has a reactance of 0.675 pu. If the ratings for calculations are changed to 33 kV, 225 MVA, determine the new generator reactance.

Question 5

Consider the common gate circuit shown below. Transistor parameters are VTH= 1V, Kn=1 mA/V2, =0

What is the small signal transconductance (in mA/V)?

Question 6

For the circuit shown in the figure find the drop across the capacitor.

Question 7

A 3-Φ Y-connected 400V, 50Hz, 4-pole induction motor has following per phase constants in Ω referred to stator.

r1 = 0.15 r2 = 0.12 Xm = 28.5

x1 = 0.45 x2 = 0.45

Compute maximum internal power developed?

Question 8

A separately excited dc motor is controlled through two single-phase semi-converters, one in the armature circuit and the other in the field circuit. Field current is constant at 2 A. Motor armature resistance is 0.8Ω and motor constant is Ka = 0.5 V-s/A rad. The converter is working from a 230 V, 50 Hz single-phase ac source. Assume armature current is ripple free at a speed of 1500 rpm. The motor current is

Question 9

Find the input output equation of the given system?

Question 10

If the circulation of the vector field F around the closed path shown in the figure is __________ (Take direction to be anti-clockwise as positive).
