About and History of EEE ( English)

EEE

Electrical and Electronic Engineering is abbreviated as EEE.

Definition:

There are two subjects electrical and electronics. They can be grouped separately. For example:

1. Electrical and 2. Electronics

Electrical:

The art or technique that deals in detail with sources of electricity flow, supplies, and various electrical circuits is called electrical.

Electronics:

Electronics is the branch of science and technology that deals with the flow of electrons through a vacuum, gas, or semiconductor.

Now, if we want to understand electrical and electronic engineering, we must first understand what is electricity? Electricity is the rate of flow of electrons in or through a conductor or metal. Therefore, the art or science that deals with the flow of electricity or electrons in detail are called Electrical and Electronics Engineering.

History

In today's world, we cannot think of anything without electricity. Electricity is widely used in every function of our life.

Electricity is a form of energy, which can be converted from one energy to another. Electricity is considered an invisible force as it cannot be seen by the eye.

And this electricity could not be discovered by any one person. The attention of many great scientists behind it is immense.

The origin of electricity is taken from the Greek word 'Electron'. The word electron means, solid stone or amber. 

In 600, the Greek philosopher Mr. Thales noticed that rubbing amber with a silk cloth produced an invisible force and the amber attracted small pieces of paper. And this invisible energy is electricity.

In the 1600s, William Gilbert discovered that not only did the rubbing of amber with a silk cloth produce an invisible force, Rather the friction of two objects produced an electric force between them.

A few years later, research on electricity was carried out by Thomas Browne, then in the late 1700s and 1800s by Otto Von Guericke, Robert Boyle, Stephen Gray, and C F de  Cisternay du Fay.

Benjamin Franklin later sold many of his financial assets to continue his research on electricity.

He believed that electricity has positive and negative components, and electricity flows through these positive and negative components.

He believed that lightning was a form of electric current, and to prove it, he tested it by blowing a coil during a lightning strike in June 1752 and attaching a key to the winding's thread to attract lightning.

Touched by a small particle of lightning, he fell to the ground, fortunately, unharmed and able to prove his hypothesis.

It was through this work of Franklin that other scientists gained more understanding of electricity.

Among them, in 1791, the biologist Luigi Galvani proved the existence of electricity in living organisms.

Then, in 1800, Italian chemist Alessandro Volta invented the first electric battery, the voltaic pi, using alternating layers of copper and zinc in a sulfuric acid solution.

Which provided a more reliable source of electrical energy than previously used electrostatic machines.

In 1820, Hans Christian's explanation of the relationship between electricity and electromagnetism and the publication of Ampere's equation of motion,

In 1831, Michael Farad invented the electronic dynamo. 

A practical and practical way of solving the problem of power generation.

Also in 1827, George Ohm analyzed electrical circuits mathematically.

And James Clark Maxwell 1868 explained the interrelationship of electricity, magnetic fields, and light.

Michael Farad used an unprotected magnet in his electronic dynamo to produce electricity by rotating a zinc disc placed between the two poles of the coil.

Since then, electricity has been used for various technological purposes.

And large generators began to be built to commercialize electricity.

As a result, the inventors of the electric bulb, Thomas Addison and Joseph Swan, both invented the electric bulb in 1879.

In the beginning, power generating stations could only generate DC current.

Among the world's first commercial power plants, Addison built a power plant in New York in 1882 to supply DC power to consumers.

However, there were some problems while supplying power to the DC system. Such as,

Power could not be supplied over long distances, supplying power beyond a certain range caused various problems like voltage drop and was also costly.

Later, under the supervision of the great inventor Nikola Tesla, an incredible change in the electricity transportation system took place.

He made an AC motor in 1887 and was able to produce high-quality AC electricity. And this AC power can be supplied to far distances without problems.

From that day till today we have been using that AC electricity.
