Sample Answer

It is candela sir. It shows the power of a light source. A normal wax candles burns with the luminous intensity of 1 candela or 1 cd.

5) Are You Aware Of Armature Reaction?

This question tests your core skills of electrical engineering.

Sample Answer

An armature means the rotation of coils of an electric motor or dynamo. An armature reaction shows the effects of such rotation on the main field. An armature conductor has the capacity to produce armature fields when current is passed through them.

6) Is There Any Fantasy Transformer? If Yes, Please Tell Us

This question tests your core skills of electrical engineering.

Sample Answer

A fantasy transformer or an ideal transformer, is the one, in which there are zero losses. The input value is similar to the output value. But this is highly theoretical as practically, there will be some losses, no matter how efficient the transformer material or conducting procedure is.

7) Do You Engage In Extra-curricular Activities Or Only Keep Studying?

We have often heard, No play and only work make a person dull. No company wants to hire a candidate who is only interested in education and is weak in physical attributes, quick-wits, personality, and communication skills. Hence, answer this in a positive manner and name a few of your major hobbies.

Sample Answer

Absolutely not sir. I am not a dull person, rather I believe I am charming and possess an adorable personality. I have always been interested in sports along with playing an active role in the drama society of our school. Taking part in state-level competitions was a common habit of mine, along with maintaining an adorable educational flow.

8) Tell Us About Elastic Potential Energy?

This questions tests your knowledge about various forms of energy.

Sample Answer

Elastic Potential energy is the energy present in any substance due to its condition. Such as Rubberband when stretched returns to its normal shape when force is removed or compressed spring, retains its normal shape when pressure is released. It is a type of potential energy amongst others.

9) Explain The Third Law of Motion?

It is highly expected that you would be asked such basic questions, in order to evaluate how efficient is your foundation.

Sample Answer

The third law of motion simply states that, for every action there will be an equal and opposite reaction. There are various practical examples to this such as, swimming, flying of a bird, movement of rockets and jets and shooting an arrow using a bow.

10) Are You Aware Of ACSR Cable?

This question would test your understanding of the various equipment used in electrical terminology.

Sample Answer

ACSR stands for Aluminium Conductor Steel Reinforced. It has a high capacity and low resistance. It is made of highly pure aluminum and is usually lightweight and corrosion-free. It is widely used as overhead power lines for the transmission and distribution of electricity.

11) Describe The Relationship Between Current And Electrons?

This question tests your core electrical engineering concepts.

Sample Answer

There is an inverse relationship between the flow of current and the flow of electrons. In a circuit, the current always flows from the negative to the positive terminal. whereas electrons flow in opposite direction i.e. positive to the negative terminal.
