Electricity is science's greatest gift 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 a dynamo machine. It is produced in a thermal power plant and also in a hydroelectric project. There are various wonders of electricity. The most important of all are the electric fan and the electric light. These two things have improved our living standards and also work efficiency. Our homes, streets, offices and shops are illuminated. It is difficult and sometimes impossible to work in an office where there is no light and fan. read comfortably in a suitably furnished room, equipped with electric light and fan.

The telegraph and telegraph device is based on electricity. It's easy to send messages to distant places. The phone also runs on electricity. Thanks to this structure, the world has become a familiar place for everyone. The fax is the latest development. (SHIVANE, 2011) Electricity is a great advantage of modern science. Electricity removed the darkness from the world and illuminated every sphere 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 everyday life we ​​need electricity. The television, the radio, the coffee grinder, the tape recorder, the heating, everything we use in the house, works only with electricity. (Chopra, 2015) Long before knowledge of electricity existed, people were aware of the shocks caused by electric fish. Ancient Egyptian texts dating back to 2750 BC referred to these fish as the "thunderer of the Nile" and described them as the "protectors" of all other fish. Electric fish were again reported millennia later by naturalists and physicists of the ancient Greeks, Romans, Arabs. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the paralyzing effect of electric shocks delivered by catfish and electric rays, and knew that such shocks could travel along conducting objects. Ancient Mediterranean cultures knew that some objects, such as amber wands, could be rubbed with cat fur to attract light objects such as feathers. (peardew, 2017) Although there have been several electricity pioneers such as Nikola Tesla and the AC induction motor, the Serbian inventor has been very important in the field of electrical engineering knowledge that keeps energy flowing around the world. it provided a dramatic improvement in the efficiency of direct current (DC) systems, which wasted energy through friction. Tesla was an inventor truly ahead of his time, a pioneer in wireless controlled drones and wireless power transmission, he even conceptualized the smartphone 100 years before the advent of the iPhone. During his lifetime, Tesla obtained 111 patents in the United States, but unfortunately his poor business acumen 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 won the War of the Currents, but American inventor Thomas Alva Edison is another prolific name in the history of electrical engineering and the choice of listing it in second place behind Tesla was difficult, but perhaps the right one. Edison may not have invented the first light bulb, but his and his staff's work at the Menlo Park Research and Development Center, 34(2), 45-52.
