What would our lives be without electricity? Ever thought of it? Horrible right?Don’t worry. It does exist and it allows us to enjoy life in so many ways.

Since electricity is a natural force that exist in our world, it didn’t have to be invented. It did, however , have to be discovered and understood. Most people give credit to Benjamin Franklin for it, but his experiments only helped establish the connection between lightning and electricity, nothing more.

Hence electricity can be defined as follows:

Flow of charge.
The physical flow of electrons, referred to as an electrical current.
A type of energy fueled by the transfer of electrons from positive and negative points within a conductor.

Benjamin Franklin had one of the greatest scientific minds of his time. He was interested in many areas of science, made many discoveries, and invented many things, including bifocal glasses. He took things a big step ahead . Came up with the idea that lightning was a form of this flowing electricity.

In 1752, Franklin conducted his famous kite experiment. In order to show that lightning was electricity, he flew a kite during a thunderstorm. He tied a metal key to the kite string to conduct the electricity. Just as he thought , electricity from the storm clouds transferred to the kite and electricity flowed down the string and gave him a shock. He was lucky enough that he did not get hurt but the experiment proved his idea!

WHO MADE THE APPLICATION OF ELECTRICITY POSSIBLE…?

It’s Thomas Alva Edison.
Thomas Alva Edison is another prolific name in the history of electrical engineering and the choice to list him second behind Tesla was a difficult one, but perhaps the right one. Edison may not have invented the first light bulb but the work of him and his staff at the Menlo Park research and development facility led to the development of the world’s first long-lasting and commercially successful light bulb. Commercializing the electric light bulb required the building of electrical transmission utilities and his Edison Illuminating Company constructed the country’s earliest electrical grids. AC may be the main form of how energy is sent from power plants to buildings, but we still use AC/DC converters in the home and direct current in modern electronic devices. By the end of his life, Edison was listed as an inventor on 1,093 U.S. patents and while it’s accepted by many that Edison relied heavily on his “mucker” research staff to develop many of these patents, his business success and futuristic vision make him an undoubted luminary in the early days of electrical engineering.

THE WIRELESS MAN….!!!

Nikola Tesla , an engineer known for designing the alternating-current (AC) electric system, which is still the predominant electrical system used across the world today. He also created the “Tesla coil,” which is still used in radio technology. Born in what is now Croatia, Tesla came to the United States in 1884 and briefly worked with Edison before the two parted ways. He sold several patent rights, including those to his AC machinery, to George Westinghouse.

DID YOU KNOW…?

Tesla and Thomas Edison grew to be fierce competitors, but in the end, Edison had the upper hand during their lifetimes. Because he was the CEO !😒

Throughout his career, Tesla discovered, designed and developed ideas for a number of important inventions — most of which were officially patented by other inventors — including dynamos and the induction motor. He was also a pioneer in the discovery of radar technology, X-ray technology, remote control and the rotating magnetic field — the basis of most AC machinery. Tesla is most well-known for his contributions in AC electricity and for the Tesla coil.

THE FATHER OF ELECTROMAGNETISM. DO YOU KNOW HIM….?

Any guesses??

Faraday began his great series of experiments in which he discovered electromagnetic induction. These experiments would form the basis of the modern electromagnetic technology that’s still used today.

In 1831, using his “induction ring”—the first electronic transformer Faraday made one of his greatest discoveries: electromagnetic induction, the “induction” or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire.

In the second series of experiments in September 1831 he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet, he obtained a continuous direct current, creating the first generator. From his experiments came devices that led to the modern electric motor, generator, and transformer.

Faraday’s laws of Electromagnetism:

FIRST LAW: Whenever a conductor is placed in a varying magnetic field an EMF gets induced across the conductor (called as induced emf ), and if the conductor is a closed circuit then induced current flows through it.
SECOND LAW: The magnitude of induced emf is equal to the rate of change of flux linkages with the coil. The flux linkages is the product of number of turns and the flux associated with the coil.
LENZ’S LAW: The direction of induced emf is such that it tends to oppose the cause producing it.

…..THE PRESENT SCENARIO……

Electricity is a major contributor to a nations economic development. It is the wheel that drives most aspects of everyday life in society. A nation is a compendium of activities and people whose progress is driven by the infrastructural components. Electricity is the source of fuel for so many sectors of an economy. We all live by electricity, our hospitals need electricity for the safe delivery of children and for surgery and other purposes. Our airports need electricity for them to work and ensure the safety. Though knowing this, we still keep on wasting the energy which takes such a long process to generate. When will we stop?
