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
