BEL Trainee Engineer Electrical Mock Test - 8 - Question 1

What does the following given circuit represent?

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 1

 

  • The circuit is sometimes called a voltage-to-frequency converter because the output frequency can be changed by changing the input voltage.
  • Pin 5 terminal is voltage control terminal and its function is to control the threshold and trigger levels.
  • Normally, the control voltage is ++2/3VCC because of the internal voltage divider. However, an external voltage can be applied to this terminal directly or through a pot.
  • The voltage across the timing capacitor is depicted in figure, which varies between +Vcontrol and ½ Vcontrol.
  • If control voltage is increased, the capacitor takes a longer to charge and discharge; the frequency, therefore, decreases.
  • Thus the fre­quency can be changed by changing the control volt­age. Incidentally, the control voltage may be made available through a pot, or it may be output of a transistor circuit, op-amp, or some other device. 

Important Point

  • A Monostable multivibrator has a stable state and a quasi-stable state. This has a trigger input to one transistor. So, one transistor changes its state automatically, while the other one needs a trigger input to change its state.
  • A Bistable multivibrator has both the two states stable. It requires two trigger pulses to be applied to change the states. Until the trigger input is given, this multivibrator cannot change its state.

BEL Trainee Engineer Electrical Mock Test - 8 - Question 2

Which of the following does not cause permanent damage to an SCR?

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 2

SCRs are constructed from silicon and are most commonly used for converting AC current to DC current (rectification), hence the name Silicon controlled rectifier.

They are also used in other applications such as regulation of power, inversion, etc.

The SCRs have an ability to handle high value of current and Voltage hence they are used in most of the industrial applications.

SCR has three terminals namely Anode (A), Cathode (K) and gate (G), and it can be turned ON or OFF by controlling the biasing conditions or the gate input.

SCR can operate in three different modes

  • Forward Blocking mode
  • Forward Conduction mode
  • Reverse Blocking mode

Among all of the options, high rate of rise of voltage does not cause permanent damage to an SCR

BEL Trainee Engineer Electrical Mock Test - 8 - Question 4

Consider a unit delay element:

Determine whether the system is memory less, causal and linear.

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 4

Concept:

A system is said to be causal if the system is dependent on the present or past inputs only but not on the future input.

A system is time-invariant if a time shift in the input signal results in an identical time shift in the output signal.

y(n) = x(n) and y(n-k) = x (n – k)

A system is said to be linear if it follows both superposition and homogeneity.

A system is said to be stable if it gives bounded input for bounded input.

Application:

y[n] = x[n – 1]

y1[n] = x1[n – 1]

y2[n] = x2[n – 1]

y3[n] = x1[n – 1] + x2[n – 1]

= y1[n] + y2[n]

The given system satisfies superposition principle.

y1[n] = ax1[n – 1] = ay[n]

The given system satisfied homogeneity principle.

As the system is satisfying both superposition and homogeneity, it is a linear system.

For the given system, the present output depends on the value of inputs only. Therefore, the system is causal.

As the output of the system is depends on the past inputs, the system is dynamic i.e. not memoryless.

BEL Trainee Engineer Electrical Mock Test - 8 - Question 5

Armature reaction in a synchronous generator at rated voltage and zero power factor leading is

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 5

Concept:

Armature Reaction: The effect of Armature (stator) flux on the flux produced by the rotor field poles is called Armature Reaction.

When the current flows through the armature winding of the alternator, a flux is produced by the resulting MMF.

This armature flux reacts with the main pole flux, causing the resultant flux to become either less than or more than the original main field flux.

Explanation:

  • Armature reaction of the alternator at zero pf lagging will be purely demagnetizing because at zero pf lagging and will be opposite to each other.

Zero pf lagging → purely demagnetizing

  • Armature reaction of the alternator at zero pf leading will be purely magnetizing because at zero pf leading and will be in the same direction to each other.

Zero pf leading → purely magnetizing

  • The generator supplies a leading load (as leading load takes the leading VAR) and in return gives lagging VAR (magnetic energy) to the generator.

In case of purely resistive load, the armature reaction is cross magnetizing only.

So, Armature reactance in a synchronous generator at rated voltage and zero power factor leading is only magnetizing.

Important Points

  • The armature reaction flux is constant in magnitude and rotates at synchronous speed.
  • The armature reaction is cross-magnetizing when the generator supplies a load at unity power factor.
  • When the generator supplies a load, at lagging power, the armature reaction is partly demagnetizing and partly cross-magnetizing.​

BEL Trainee Engineer Electrical Mock Test - 8 - Question 6

In a power MOSFET, pinch-off occurs when (VDS is the drain to source voltage, VGS is the gate to source voltage VT is the threshold voltage):

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 6

As shown in the above figure in a power MOSFET, pinch-off occurs when VDS = VGS - VT

Where, VDS = Drain to source voltage

​VGS = Gate to source voltage

VT = Threshold voltage

  • In power MOSFET when VDS < />GS - VT, then power MOSFET works in the triode region.
  • In power MOSFET when VDS > VGS - VT, then power MOSFET works in the saturation region.
BEL Trainee Engineer Electrical Mock Test - 8 - Question 7
Out of the following. what happens to the overall gain of the system of a closed loop control system with positive value of feedback gain?
Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 7

Concept of Feedback System:

  • A Feedback System is one in which the output signal is sampled and then fed back to the input to form an error signal that drives the system, and depending on the type of feedback used, the feedback signal which is mixed with the systems input signal, can be either a voltage or a current.
  • Feedback will always change the performance of a system and feedback arrangements can be either positive (regenerative) or negative (degenerative) type feedback systems.
  • If the feedback loop around the system produces a loop-gain that is negative, the feedback is said to be negative or degenerative with the main effect of the negative feedback is in reducing the system’s gain.
  • If however, the gain around the loop is positive, the system is said to have positive feedback or regenerative feedback. The effect of positive feedback is to increase the gain which can cause a system to become unstable and oscillate especially if GH = -1.

Positive feedback:

  • In an open-loop system, we do not have any feedback path but in a closed-loop system, we have a feedback path.
  • The transfer function of the closed-loop transfer function, with positive feedback, is given by
  • The overall gain of the transfer function increases with positive feedback.

Parseval’s relation for a periodic signal relates
Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 8

Parseval's Theorem:

For continuous-time, periodic signal, the energy is given by:

Where ak is the Fourier series coefficient of x(t), and T is the period of the signal.

For average power in one period of the periodic signal x(t), we write:

is the average power in the kth harmonic of x(t).

∴ Parseval's relation states that the total average power in a periodic signal equals the sum of the average powers in all of its harmonic components.

BEL Trainee Engineer Electrical Mock Test - 8 - Question 15

In magnetic circuits, due to fringing effect, the following is true if Bc represents core flux density and Bg represents average air gap flux density.

Detailed Solution for BEL Trainee Engineer Electrical Mock Test - 8 - Question 15

Magnetic Fringing:

  • One of the properties of the magnetic lines of force states that there is a force of repulsion between the lines of forces which are parallel to each other and are in the same direction
  • This repulsive force will cause the magnetic flux to spread out or bulge out at the edges of the air gap as shown in the figure
  • The tendency of the magnetic flux to spread out at the edges of the air gap is called Magnetic Fringing

Effects of magnetic fringing:

  • Due to the spreading of flux at the edges of the air gap the effective cross-sectional area of the air gap is increased.
  • Due to an increased cross-sectional area, the flux density (B) in the air gap is reduced.

Leakage flux and magnetic fringing are an undesirable phenomenon. They can be reduced by selecting high-quality magnetic material and making the air gap as narrow as possible.

Due to the spreading of flux at the edges of the air gap (due to magnetic fringing) the effective cross-sectional area of the air gap increases.

Therefore, Bc > Bg

To determine the size of a monitor, we measure the screen diagonally, from the top left corner to the bottom right corner. Here's a detailed explanation:
Diagonal Measurement:
- The size of a monitor is typically measured diagonally because it provides an accurate representation of the screen's actual size.
- The diagonal measurement is obtained by measuring the distance from the top left corner of the screen to the bottom right corner in a straight line.
- This measurement helps us understand the physical size of the screen and is commonly used to compare and select monitors.
Other Measurements:
- While diagonal measurement is the standard for determining monitor size, other measurements are also important for specific purposes.
- Vertical measurement refers to the distance from the top to the bottom of the screen, which is essential for understanding the screen's height.
- Horizontal measurement refers to the distance from the left to the right of the screen, which helps in determining the screen's width.
- However, these measurements alone do not provide a comprehensive understanding of the monitor's size.
Conclusion:
In conclusion, the size of a monitor is determined by measuring the screen diagonally, from the top left corner to the bottom right corner. This measurement provides an accurate representation of the screen's size and is commonly used for comparing and selecting monitors.
