Re: APTRANSCO Electrical Assistant Engineer previous year question papers

As you want to get the APTRANSCO Electrical Assistant Engineer previous year question papers so here it is for you:

Some content of the file has been given here:

1. A voltage waveform v(t)= 12 t2 is applied across a 1H inductor for t>=0 with initial current through it
being zero. The current through the inductor for t>=0 is given by-----------(4t3)
2. Two incandescent light bulbs fo 40w and 60w rating are connected in series across the mains.
Then--------(the 40 bulb glows brighter)
3. Given two coupled inductors L1 and L2, their mutual inductances M satisfies-----(M<=sqrt(L1L2)
4. Consider the star network. The resistance between terminals A and B with C open 6ohms,
between terminals B and C with A open is 11ohms, and between terminals C and A with B open is
9ohms. Then ------------(Ra=2, Rb=4, Rc=7)
5. In a series RLC circuit at resonance, the magnitude of the voltage developed across the capacitor---
---( can be greater than the input voltage, however, it is 900 out of phase with the input voltage)
6. A two port device is defined by the following pair of quations:
i1=2v1+v2 and i2=v1+v2 its impedance parameters (z11, z12, z21, z22) are-----(1,-1,-1,2)
7. The impulse response of an initially relaxed linear system is e-2tu(t).to produce a response of
te-2tu(t), the input must be equal to--------(e-2t u(t))
8. The no of roots on the equation 2s4+s3+3s2+5s+7=0 that lie in the right half of s plane is-------(2)
9. For a feedback control system of type 2, the steady state error for a ramp input is-------(zero)
10. The output of a linear time invariant control system is c(t) for a certain input r(t). if r(t) is modified
by passing it through a block whose transfer function is e-s and then applied to the system, the modified
output of the system would be-----------(c(t-1)u(t-1)
11. The phase lead compensation used to-----(decreases both rise time and overshoot)
12. Consider two buses connected by an impedance of (0+j5)ohm. The bus 1 voltage is 100/300 v, and
bus 2 voltage is 100/00 v. the real and reactive power supplied by bus 1, resp are……….(1000w, 268 VAr)
13. For a fixed value of complex power flow in a transmission line having a sending end voltage V, the
real power loss will be proportional to-----------(1/V2).

For more detailed information I am uploading a PDF file which is free to download:
