Electricity is the greatest gift of science to humanity. We have reached a point in our civilization where electricity is used for all purposes. Electricity is a source of energy. It is produced by a battery or a coil of wires or by a dynamo machine. It is produced in thermal power plants and also in hydroelectric projects. There are various wonders of electricity. The most important of all is the electric fan and electric light. These two things have improved our standard of living as well as work efficiency. Our homes, roads, offices and stores are lit. It is difficult, if not impossible, to work in an office without lights or fans. read comfortably in a properly equipped room with electric light and fan. Say no to plagiarism.

It's easy to send messages to remote locations. The phone also runs on electricity. With this facility, the world has become a familiar place for everyone. The fax machine is the latest development. (SHIVANE, 2011) Electricity is a great boon of modern science. Electricity removed the darkness from the world and illuminated all spheres of human activity. Today, life without electricity is almost impossible. Modern life has become so modern and mechanical that even for all the little things of daily life we ​​need electricity. The television, the radio, the shredder, the tape recorder, the heater, everything we use at home runs solely on electricity. (Chopra, 2015) Long before any knowledge of electricity, people were aware of the shocks caused by electric fish. Ancient Egyptian texts dating back to 2750 BCE referred to these fish as "thunder of the Nile" and described them as the "protectors" of all other fish. Electric fish were reported again millennia later by Greek, Roman, and Arab naturalists and physicists. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by catfish and electric rays, and knew that such shocks could propagate along conductive objects. Ancient cultures around the Mediterranean knew that certain objects, such as amber sticks, could be rubbed with cat fur to attract lightweight objects like feathers. (peardew, 2017) Although there were different pioneers of electricity such as Nikola Tesla and the AC induction motor, the Serbian-born inventor was very important in the field of electrical engineering knowledge that allow energy to flow throughout the world. brought a considerable improvement to the efficiency of direct current (DC) systems, which wasted energy through friction. Tesla was an inventor truly ahead of his time, a pioneer of wirelessly controlled drones and wireless power transmissions. He even conceptualized the smartphone 100 years before the advent of the iPhone. During his lifetime, Tesla obtained 111 U.S. patents, but unfortunately his poor business sense led him to miss out on the financial successes of other inventors of the time. (Brachmann, 2017) Thomas Edison and Incandescent Lighting – Tesla's AC systems may have finally won the war of currents, but American inventor Thomas Alva Edison is another prolific name in the history of electrical engineering and., 34(2), 45-52.
