*30 question- Aptitude

*3 question-Passage

*Some more topics which you have to learn.
*Data interpretation
*General knowledge
*Compound interest
*Height and distance
*Solid state and electronics
*Circuit theory
*Network Theorems
*Digital signal processing
*Microprocessors
You have to prepare for all the above topics.

And you can download papers from below givensite.

Dear friend there are mainly three subjects which is asked in exams.
First is Quantitative Ability
Second is Verbal Ability
Third is Data Interpretation.

If you have command over these three subjects then you will surely get succeed.

For model question papers visit the site of placement papers.

Best of luck

1.Paper base bakelite copper clad sheet
2. Glass epoxy copper clad sheet

17. Many switch contacts use silver as the material because

1. It is a good electrical conductor with low contact resistance
2. Silver does not tarnish
3. It is easily shaped as per requirement
4. It is very hard and does not wear off


18. A resistance of approximate value 85W is to be measured by using an ammeter of range 0-1 A having a resistance of 20 W and voltmeter of range 0-50V having a resistance of 5000W. Two arrangement for the measurement are shown in the figure below. Which method would you recommend?

20. It is proposed to fabricate a simple Ohm meter for measuring resistor values. A milliammeter with an internal resistance of 50 W is available. Choosing a configuration using a 3 V battery, a large resistance and the ammeter in a loop, the unknown resistor is proposed to be measured by noting the current initially and then connecting the unknown resistor across the ammeter. If the ratio of the two current is 2, what is the value of the unknown resistor (rn W ) ?

a. 3000 b. 150 c. 100 d. 50

21.The current I flowing into the branch indicated by an arrow in the circuit shown is equal to


a. 2 Amp b. 0.5 Amp c. 1 Amp d. 0.25 Amp

22. For the circuit shown, the maximum power is delivered to the load resistance RL when the value of Rg is

a. 2 ohms b. zero c. 10 ohms d. infinity

23. A signal generator is available in the laboratory, which is in good condition except for the attenuator dial which has got displaced. In order to calibrate this, a high frequency oscilloscope is available. At a particular setting of the knob an open circuit voltage of 450 mV rms is measured. If the impedance of the generator is 50 ohms, the setting of the attenuator dial is to be adjusted for

a. 6 dBm b. 1 dBm c. 0 dBm d. 10 dBm

24. The relation Loge (X + Loge (1 + X) = 0 also means that

1. X2 + X + 1 = 0

2. X2 + X - 1 = 0

3. X2 + X + e = 0

4. X2 + X – e = 0

25. The Laplace transform of the function f(t) = cos wt is

1. w/(s2 + w2)

2. s2/(s2 - w2)

3. w2/(s2 + w2)

4. s/(s2 + w2)

26. If a = b = c, one value of X which satisfies the equation

=0 is given by

a. x=a b. x=b c. x=c d. x=0

27. An LC oscillator is being analysed. If the LC tank circuit (with quality factor = Q) is isolated from the amplifying device, the impedance at the resonant frequency as measured looking into the amplifier will be

1. Q r [LC]1/2

2. ½ rp r [LC]1/2

3. – Q r[LC]1/2

4. Q r [LC]1/2


28. A battery eliminator is required to be constructed and an assortment of rectifiers, resistors and capacitors is available. However, the step down transformer available has no center tap. The following configurations for the rectifier are feasible. The one giving the lowest ripple will be

1. Full wave rectifier
2. Half wave rectified
3. Bridge rectifier
4. None

29. Chokes used in rectifier filter circuits are wound on a core with a small air gap. This is done in order to

1. Get as high an inductance as possible
2. Prevent saturation of the core
3. Absorb the ripple effectively
4. Prevent loading the transformer

30. An integrated circuit linear regulator is used at the output of a power supply having a ripple of 1 V rms. Assuming that the IC represents a typical design generally available, the output rms ripple to be expected will be

a.. 0.1 V rms b. 0.1 mV c. 100 mV d. 1.0 V rms

best of luck.......

18. A resistance of approximate value 85W is to be measured by using an ammeter of range 0-1 A having a resistance of 20 W and voltmeter of range 0-50V having a resistance of 5000W. Two arrangement for the measurement are shown in the figure below. Which method would you recommend?

1. Method X
2. Method Y
3. Either X or Y
4. Neither X nor Y


19. The value of capacitance across points A & B in the circuit shown below is (in microfarads)

a. .3 b. 1 c. 0.67 d. 0.33

20. It is proposed to fabricate a simple Ohm meter for measuring resistor values. A milliammeter with an internal resistance of 50 W is available. Choosing a configuration using a 3 V battery, a large resistance and the ammeter in a loop, the unknown resistor is proposed to be measured by noting the current initially and then connecting the unknown resistor across the ammeter. If the ratio of the two current is 2, what is the value of the unknown resistor (rn W ) ?

a. 3000 b. 150 c. 100 d. 50

21.The current I flowing into the branch indicated by an arrow in the circuit shown is equal to


a. 2 Amp b. 0.5 Amp c. 1 Amp d. 0.25 Amp

22. For the circuit shown, the maximum power is delivered to the load resistance RL when the value of Rg is

a. 2 ohms b. zero c. 10 ohms d. infinity

23. A signal generator is available in the laboratory, which is in good condition except for the attenuator dial which has got displaced. In order to calibrate this, a high frequency oscilloscope is available. At a particular setting of the knob an open circuit voltage of 450 mV rms is measured. If the impedance of the generator is 50 ohms, the setting of the attenuator dial is to be adjusted for

a. 6 dBm b. 1 dBm c. 0 dBm d. 10 dBm

24. The relation Loge (X + Loge (1 + X) = 0 also means that

1. X2 + X + 1 = 0

2. X2 + X - 1 = 0

3. X2 + X + e = 0

4. X2 + X – e = 0

25. The Laplace transform of the function f(t) = cos wt is

1. w/(s2 + w2)

2. s2/(s2 - w2)

3. w2/(s2 + w2)

4. s/(s2 + w2)

26. If a = b = c, one value of X which satisfies the equation

=0 is given by

a. x=a b. x=b c. x=c d. x=0

27. An LC oscillator is being analysed. If the LC tank circuit (with quality factor = Q) is isolated from the amplifying device, the impedance at the resonant frequency as measured looking into the amplifier will be

1. Q r [LC]1/2

2. ½ rp r [LC]1/2

3. – Q r[LC]1/2

4. Q r [LC]1/2


28. A battery eliminator is required to be constructed and an assortment of rectifiers, resistors and capacitors is available. However, the step down transformer available has no center tap. The following configurations for the rectifier are feasible. The one giving the lowest ripple will be

1. Full wave rectifier
2. Half wave rectified
3. Bridge rectifier
4. None

29. Chokes used in rectifier filter circuits are wound on a core with a small air gap. This is done in order to

1. Get as high an inductance as possible
2. Prevent saturation of the core
3. Absorb the ripple effectively
4. Prevent loading the transformer

30. An integrated circuit linear regulator is used at the output of a power supply having a ripple of 1 V rms. Assuming that the IC represents a typical design generally available, the output rms ripple to be expected will be

a.. 0.1 V rms b. 0.1 mV c. 100 mV d. 1.0 V rms

best of luck.......
