Q1. In 3 dimension plane if X & Y is presente, what is the name of another one?

Ans.

The name of the third dimension in a 3D plane is Z.

Ans.

Coordinate in Bengali means সমন্বয় (sômnôyô)

Coordinate means সমন্বয় (sômnôyô) in Bengali language
It refers to working together or in harmony with others
For example, in electrical engineering, coordinate protection is a system where different protective relays work together to protect a power system

Ans.

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary, wrapped around a magnetic core.
When an AC voltage is applied to the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.
Transformers are used...read more

Ans.

The unit of transformer rating is in volt-amperes (VA) or kilovolt-amperes (kVA).

Transformer rating is the maximum power that can be transferred from the primary to the secondary winding.
It is used to determine the size and capacity of the transformer.
The rating is usually mentioned on the nameplate of the transformer.
For example, a transformer with a rating of 500 kVA can handle a maximum power of 500,000 VA.
The rating is based on the voltage, current, and frequency of the t...read more

Are these interview questions helpful?

Ans.

My field is electrical engineering.

I have a degree in electrical engineering.
I have experience working with electrical systems and circuits.
I am knowledgeable in areas such as power distribution, control systems, and electronics.
I have worked on projects involving electrical design and troubleshooting.

Ans.

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.
It is applicable to all types of circuits, including AC and DC circuits.
Ohm's law helps in calculating the current, voltage, and resistance in a circuit.
For example, if the voltage across a resistor is 10 volts and the resistance...read more

Ans.

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

Transformers consist of two coils of wire, known as the primary and secondary coils, which are usually wound around a core made of iron or steel.
They work on the principle of electromagnetic induction, where a changing current in the primary coil induces a voltage in the secondary coil.
Transformers are used to step up or step down voltage levels i...read more
