Sample EC6202 Electronic Devices and Circuits Important questions:

Part A

1. Define Knee Voltage of a diode

The minimum voltage at which the diode starts conducting and current starts increasing Exponentially is called knee voltage of a diode.

2. What is peak inverse voltage

In reverse biased, opposite polarity voltage appears across diode. The maximum voltage which diode can withstand without breakdown is called peak inverse voltage. (EC6202 Electronic Devices and Circuits Important questions)

3. Differentiate drift and diffusion current

When a voltage is applied to a material, the free electrons move towards the positive of the battery. While moving them collide with the adjacent atoms and keep changing their directions randomly. In case of diffusion current, the external voltage is not required.

4. What is a PN Junction diode

There are two electrodes each from p-type and n-type materials and due to these two electrodes; the device is called a diode. It conducts only in one direction.

Sample EE6302 Electromagnetic Theory Important questions:

1. State stokes theorem.

The line integral of a vector around a closed path is equal to the surface integral
of the normal component of its curl over any surface bounded by the path
∫H.dl = ∫ ∫ (ΔxH)ds
Where, H=Magnetic field intensity

(ee6302 electromagnetic theory important questions)

2. State the condition for the vector F to be solenoidal.

Where, F=A i + B i + C i

3. State the condition for the vector F to be irrotational.

ΔxF =0
Where, F=A i + B i + C i

4. Give the relationship between potential gradiant and electric field.

E= – ΔV
Where, E=Electric Field Intensity

5. What is the physical significance of div D ?

The divergence of a vector flux density is electric flux per unit volume leaving a small volume. This is equal to the volume charge density. (ee6302 electromagnetic theory important questions)

6.What are the sources of electric field and magnetic field?

Stationary charges produce electric field that are constant in time, hence the term
electrostatics. Moving charges produce magnetic fields hence the term magneto statics. (ee6302 electromagnetic theory important questions)

7. State Divergence Theorem. 

The integral of the divergence of a vector over a volume v is equal to the surface
integral of the normal component of the vector over the surface bounded by the volume.
∫∫Δ.F ds = ∫∫∫ F dv
Where, F=A i + B i + C i (ee6302 electromagnetic theory important questions)

8. Define divergence.

The divergence of a vector F at any point is defined as the limit of its surface integral per unit volume as the volume enclosed by the surface around the point shrinks to zero. (ee6302 electromagnetic theory important questions)

9. State coulombs law.

Coulombs law states that the force (F) between any two point charges (Q1 and Q2) is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance ® between them. It is directed along the line joining the two charges.

Sample EE6301 Digital Logic Circuits Important questions:

Part – A 2 Marks and part B 16 Marks

1. Where the digital systems are used?

Digital systems are used extensively in computation and data processing, control systems, Communications and measurements. Since digital systems are capable of greater accuracy and reliability than analog systems, many tasks formerly done by analog are now being performed digitally.

2. What is the difference between analog and digital systems?

In a digital system the physical quantities or signals can assume only discrete values, while in analog systems the physical quantities or signals vary continuously over a specified range. (EE6301 digital logic circuits important questions)

3. What is a binary number system and Why are binary numbers used in digital systems?

The number system with base (or radix) two is known as the binary number system. Only two symbols are used to represent the numbers in the system and these are 0 and 1.The outputs of the switching devices used in digital systems assume only two different values. Hence it is natural to use binary numbers internally in digital systems.

4. What is the difference between binary code and BCD? (EE6301 digital logic circuits important questions)

Binary:

i. Any distinct element can be represented by a binary code.
ii. No limitation for the minimum or maximum number of elements required for coding the element.

BCD:

i. Only a decimal digit can be represented.
ii. It is a four bit representation.

Values decide the standard of behavior. Some universally accepted values are freedom justice and equality. Other principles of values are love, care, honesty, integrity, self respect.

2. What are ethical values?

Trustworthiness, respect, responsibility, fairness, caring is ethical values

(GE6075 Professional Ethics in Engineering Important questions)

3. Distinguish values from ethics and culture.

Values are mainly related to individuals and since they are related to justice, they remain the some for every one. E.g. truth, honesty, empathy, self respect.
Values do not change from individual to individual. Ethics is common to a group of individuals; the group may be religious or professional. Ethics is mostly based on some code or law and judgment of any action is based individual to individual f conduct or law. Ethics change from Culture commonly refers to conduct of a group. E.g system of worship, marriage It may differ from society to society, nation to nation or religion to religion.

4. What is integrity?

Integrity is the unity of character based on moral values. Consistency in attitudes, emotions and conduct in relations to morally justified actions and values are also the part of integrity of individual. It implies honesty, trustworthiness.

(GE6075 Professional Ethics in Engineering Important questions)

5. Define work ethics

By one’s work one cannot harm others. Any worker cannot escape accountability. Worker has the moral responsibility to see that no other person’s right, private or freedom is impaired or transgressed.

6. What is service learning?

Service learning tells that one has moral responsibility to increase the desirable effects and to decrease the harmful effects. Any service should increase the desirable result.
