No one invented electricity, but it was discovered by humans
The first studies into the production of electricity were conducted by the Greek philosopher Thales of Miletus in the 6th century BCE. He experimented with amber rods, now known as the triboelectric effect, which can lift light objects and generate sparks. However, this method was extremely inefficient.
In the 18th century, the invention of the voltaic pile provided a viable source of electricity. This was further improved upon by Alessandro Volta, who created the first electrical battery in 1800, providing scientists with a more reliable source of electrical energy.
In the 19th century, there were significant advancements in understanding electricity and its applications. Scientists such as Hans Christian Ørsted, André-Marie Ampère, Michael Faraday, Georg Ohm, and Thomas Edison made groundbreaking contributions to the field. Benjamin Franklin, an 18th-century American statesman, is also credited by many for his work in understanding and applying electricity. Franklin defined a positive charge as the charge acquired by a glass rod when rubbed with silk cloth.
Nikola Tesla, a Serbian-American engineer, and inventor also made significant contributions to the design of the modern alternating current (AC) electricity supply system.
Therefore, while no single person can be credited with inventing electricity, these pioneers and many others played a crucial role in discovering and harnessing its power for human benefit.

Benjamin Franklin is most credited for discovering electricity in 1752
While Benjamin Franklin is often credited with discovering electricity, it is important to note that he did not discover electricity per se, as electrical forces had been recognized for centuries before his famous kite experiment in 1752.
Franklin's experiment, however, was a pivotal moment in the history of electricity. On a stormy afternoon in June 1752, Franklin, along with his son William, flew a kite made of a large silk handkerchief, with hemp and silk strings, to which a key was attached. As the kite encountered small amounts of electricity in the storm clouds, Franklin touched the key, causing the threads on the string to stand on end. The electric charge was then collected in a Leyden jar, an early form of capacitor capable of storing a high-voltage electric charge. Through this experiment, Franklin demonstrated the connection between lightning and electricity, proving that they were the result of the same phenomenon.
Franklin's contributions to our understanding of electricity extended beyond his kite experiment. He is credited with coining terms such as "attraction" and "repulsion" to describe the natural properties of electricity and introduced other relevant terminology. Franklin also turned his home in Philadelphia into an electrical laboratory, conducting various experiments with instruments crafted from household items. For example, he rigged a group of electric bells to ring when electricity filled the atmosphere, and he observed the small sparks that jumped between the wires, causing the bells to ring softly.
While Franklin did not invent electricity, his experiments and theories significantly advanced our understanding of this phenomenon. His work built upon that of earlier scientists, such as the ancient Greeks, who had experimented with static electricity, and he, in turn, laid the foundation for further advancements in electrical engineering by later scientists such as Alessandro Volta, Michael Faraday, and Thomas Edison.

Thomas Edison is renowned for his contributions to the practical application of electricity
Edison's work in the field of telegraphy, where he worked as a telegraph operator, was key to his initial success. This knowledge, together with his studies in chemistry at the Cooper Union, allowed him to make his early fortune with the stock ticker, the first electricity-based broadcast system. He also developed the quadruplex, the first system to simultaneously transmit four messages through a single wire. Edison was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees.
Edison's most famous invention, the first practical electric incandescent lamp, was publicly demonstrated at his Menlo Park, New Jersey, laboratory on New Year's Eve 1879. This invention was the culmination of Edison's work in putting together a whole system of electric lighting, including light bulbs, electricity generators, wires, fixtures (lamps, sockets, switches), and more. Edison filled more than 40,000 pages with notes before he finally had a bulb that withstood a 40-hour test in his laboratory.
Edison also invented a highly sensitive device that he named the tasimeter, which measured infrared radiation. He created this device to measure the heat from the solar corona during the total solar eclipse of July 29, 1878. Although it was not patented, as Edison saw no practical mass-market application for it, it demonstrated his curiosity and drive to innovate.
In addition to his work with electricity, Edison also contributed to other fields. He invented the first electrical vote recorder, designed for the Massachusetts State Legislature, although it was not adopted. He also worked on improving storage batteries for electric vehicles, believing that they were superior to gasoline or steam-powered vehicles. Although his battery technology was ultimately outpaced by the development of gasoline engines, his batteries found many other uses, such as in railroad signals, miners' headlamps, and marine buoys.

Nikola Tesla made advancements in electrical engineering, pioneering alternating current (AC) power transmission
The history of electricity is a long and fascinating one, dating back to the 6th century BC when the Greek philosopher Thales of Miletus experimented with amber rods, producing sparks of electricity through what is now known as the triboelectric effect. However, it was Nikola Tesla, a Serbian-American engineer, inventor, and physicist, who made groundbreaking advancements in electrical engineering and power transmission.
Born in 1856 in the Austrian Empire (now Austria-Hungary), Tesla first studied engineering and physics in the 1870s, sparking his interest in electricity. He immigrated to the United States in 1884 and began working on his revolutionary ideas. Tesla is best known for his development of the alternating current (AC) electrical system, which can transmit electricity over much greater distances than direct current (DC).
Tesla's AC induction motor and polyphase AC patents were licensed by Westinghouse Electric in 1888, earning him significant recognition and financial gain. The induction motor was a key component of Tesla's overall system, which also included a generator, transformers, transmission layout, and lighting. This polyphase alternating-current system provided the basic elements for electrical production and utilization, and it remains the foundation of our modern AC power system.
Tesla's work laid the groundwork for modern electrical engineering and power generation. He was a pioneer in the field, with his inventions and innovations paving the way for widespread industrial and manufacturing uses of electricity. Tesla's system was first used at the World's Columbian Exposition in Chicago in 1893 and later at Niagara Falls in 1896, powering the world's first large hydroelectric plant. His work with radio-frequency waves also contributed to the development of modern radio, and he received numerous patents for his inventions, including the Tesla coil, which is still used in various electronic devices today.
Nikola Tesla's contributions to electrical engineering and his pioneering work in alternating current power transmission have had a lasting impact on the world, shaping the way we use and generate electricity today.

Alessandro Volta invented the first electrical battery in 1800
Alessandro Volta invented the first electrical battery, also known as the voltaic pile, in 1800. The battery was a simple and reliable source of electric current, which allowed scientists to study electricity better than they could with previous sources.
The invention of the voltaic pile was the culmination of years of experimentation and study by Volta. He first became interested in electricity as a teenager and decided to pursue his passion for physics. He left school early and did not attend university, but he began working and corresponding with scientists conducting research in the electricity arena, including Abbott Nollet in Paris and Giambatista Beccaria in Turin. In 1774, Volta began teaching in a local school in Como while continuing his experiments with electricity. He made several notable accomplishments within that decade, including improving and popularizing the perpetual electrophorus, a device that produces charges of static electricity and can transfer charge to other objects.
In 1780, Volta became engaged in a debate with Italian physician and scientist Luigi Galvani, which would inspire his development of the voltaic pile. Galvani had been experimenting with dissected frogs' legs, still attached to their spinal cords and hung on brass or iron hooks. He noted that when touched with a piece of another metal, the frog legs would twitch; he believed he had discovered a new form of electricity generated by those legs, which he called "animal electricity." Volta refuted this theory and insisted that the animals' legs were not producing the electricity but only reacting to it. He believed that the metals used in Galvani's experiments were generating the current and set out to prove him wrong.
Volta began experimenting with metals alone in 1792. He would detect the weak flow of electricity between disks of different metals by placing them on his tongue. He found that animal tissue was not needed to produce a current, and in 1800, he unveiled the first-ever electric pile through a letter to the president of the Royal Society of London. The device consisted of a stack of alternating silver and zinc wafers, with pieces of brine-soaked cloth in between. When a wire was connected to both ends of the pile, a current flowed. This was essentially the world's first battery.
