While electricity is a natural phenomenon that cannot be invented, humans have been harnessing its power for about 250 years. The ancient Greeks discovered the notion of electrical charge over 2,600 years ago, and ancient texts show that Egyptians knew about the shock-inducing properties of electric fish. However, the first major breakthrough in electricity occurred when British scientist Michael Faraday discovered the basic principles of electricity generation in 1831. Since then, pioneers such as Benjamin Franklin, Alessandro Volta, Nikola Tesla, and Thomas Edison have made key contributions to our understanding and harnessing of electrical energy, leading to the electric power systems we rely on today.

What You'll Learn
Benjamin Franklin's kite experiment
While electricity as a physical phenomenon had been identified thousands of years before Benjamin Franklin, he is often credited with being the first to harness it. This is due to his famous kite experiment, which demonstrated that lightning is a form of electricity.
Franklin's kite experiment was first proposed in 1752, with the assistance of his son, William. The experiment involved flying a kite with a key attached to its string during a thunderstorm to see if it would draw an electrical charge. The kite was constructed using a large silk handkerchief, a hemp string, and a silk string. The hemp string, wetted by the rain, would conduct an electrical charge quickly, while the silk string, kept dry, would not.
Franklin's experiment did not involve his kite being struck by lightning. Instead, the kite picked up the ambient electrical charge from the storm. This demonstrated the connection between lightning and electricity and helped prove that lightning was a form of electricity that could be harnessed.
Franklin's own description of the event appeared in the Pennsylvania Gazette on October 19, 1752. In it, he gave instructions for recreating the experiment, stating that as the thunder clouds come over the kite, the pointed wire will draw the electric fire, and the loose filaments of the twine will stand out and be attracted by an approaching finger.
While some have questioned whether the experiment took place at all, it helped pave the way for further discoveries and our modern understanding of electricity.

Ancient Egyptians and electric eels
While electricity as a form of energy cannot be invented, humans have been harnessing its power for about 250 years. The ancient Egyptians knew that some species of electric fish, such as the electric Nile catfish, could trigger shocks in the body. They likely used the electric catfish to treat headaches and nerve pain—a practice known as ichthyoelectroanalgesia—which remained in medical use until the late 1600s. The ancient Egyptians called the electric fish "the thunderer of the Nile". The first known depiction of an electric catfish is on a slate palette of the predynastic Egyptian ruler Narmer, dating back to around 3100 BC. Electric fishes were also known to Aristotle, Theophrastus, and Pliny the Elder, among other classical authors.
In the 18th century, the abilities of the torpedo ray and the electric eel were investigated by scientists including Hugh Williamson and John Walsh. In 1776, John Walsh demonstrated that electric eels could spark. In 1839, the chemist Michael Faraday extensively tested the electrical properties of an electric eel imported from Suriname. He measured the electrical impulses produced by the animal by pressing shaped copper paddles and saddles against the specimen. Through this method, he determined and quantified the direction and magnitude of the electric current.
Carl Sachs, a German zoologist, was sent to Latin America to study the electric eel. He took with him a galvanometer and electrodes to measure the fish's electric organ discharge. He published his research on the fish, including his discovery of what is now called Sachs' organ, in 1877. Artist's impressions from 1800 depict Alexander von Humboldt hunting electric eels using a herd of horses.

Baghdad battery
The Baghdad Battery, also known as the Parthian Battery, is an ancient artefact discovered in 1936 by an expedition led by Dr Wilhelm König of the Iraq Museum in Baghdad. The battery consists of a clay jar, a copper cylinder, and an iron rod, and is believed to be around 2,000 years old, dating back to the 1st century AD during the occupation of the Parthian Empire in the region.
The function and purpose of the Baghdad Battery have been the subject of much speculation. Some experts believe that it was used for electroplating, a process of coating one metal with a layer of another metal, such as gold plating on silver. This theory is based on the idea that if the clay jar was used as an electrical cell, the copper cylinder would have gone into solution in the liquid, resulting in copious amounts of copper salts in the jar. However, there is no conclusive evidence to support this theory, and some experts argue that the objects in question were fire-gilded with mercury, a common practice in the region at the time.
Another theory suggests that the Baghdad Battery was used for magical or religious purposes. Similar vessels found in Seleucia and Ctesiphon were associated with magic and contained conjurations, blessings, and the like written on papyrus. The clay jar of the Baghdad Battery was found in proximity to magical bowls, further supporting the idea that it may have been used in ritual practices.
The true function of the Baghdad Battery remains a mystery, but its discovery provides valuable insights into the technological capabilities and innovations of ancient civilizations. While the battery may not have been used to power electrical devices as we know them today, it demonstrates a fundamental understanding of electrical principles and the potential for harnessing electrical energy.
It is worth noting that the concept of electricity has been studied for thousands of years, with the Greeks being the first to discover the notion of electrical charge over 2,600 years ago. However, the practical harnessing of electricity is a more recent development, with the first practical incandescent lightbulb being unveiled by Thomas Edison in 1878, and the basic principles of electricity generation being discovered by Michael Faraday in 1831.

Thomas Edison's lightbulb
While electricity cannot be invented, Thomas Edison is credited with developing a system for distributing electricity to homes and businesses, which revolutionised the way we live and work.
Thomas Edison, born in Ohio in 1847, was one of the most well-known inventors of all time. Edison's mother, Nancy, encouraged his early interest in chemistry and electronics, giving him books on the subjects. Edison set up a laboratory in the basement of his family's Michigan home, where he spent most of his time experimenting.
Edison's work on the telegraph inspired some of his earliest inventions, including the automatic telegraph, duplex telegraph, and message printer. In 1875, Edison set up a laboratory in Menlo Park, New Jersey, where he worked on developing an efficient incandescent lamp. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Edison's lamp consisted of a filament housed in a glass vacuum bulb. He had his own glass-blowing shed where the fragile bulbs were carefully crafted for his experiments.
By January 1879, Edison had built his first high-resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. However, the lamp only burned for a few hours. Edison tested thousands of other materials for the filament to improve the bulb. In 1878, Edison unveiled the first practical incandescent lightbulb that could generate light for hours on end.

Nikola Tesla's AC power
While electricity as a form of energy cannot be invented, Serbian-American engineer and inventor Nikola Tesla is credited with pioneering work with alternating current (AC) electricity. Tesla was born in 1856 in the Austrian Empire (present-day Croatia) and studied engineering and physics in the 1870s. He gained practical experience in the early 1880s, working in telephony and at Continental Edison in the emerging electric power industry. In 1884, he immigrated to the United States, where he continued his work in electricity and obtained numerous patents for his inventions.
Tesla's most notable contributions to the field of electricity include his work with the polyphase AC system and the AC induction motor. In 1888, he licensed his AC induction motor and related polyphase AC patents to Westinghouse Electric. This system consisted of a generator, transformers, transmission layout, and motor and lights, providing the basic elements for electrical production and utilization. The AC power system that Tesla helped develop remains largely unchanged today and is still used worldwide.
One of the key advantages of Tesla's AC system was its ability to transmit electricity over long distances with minimal energy loss. This made it ideal for large-scale power generation and distribution. In 1893, Tesla's AC system was used to light the World's Columbian Exposition in Chicago, demonstrating its effectiveness and potential for widespread adoption. Subsequently, in 1896, his system was implemented at Niagara Falls in the world's first large-scale hydroelectric plant, further solidifying the importance of AC power.
In addition to his work with AC power, Tesla also made significant contributions to wireless transmission technology. He conducted experiments with radio-frequency waves, laying the foundation for modern radio. Additionally, he suggested the possibility of using radio waves to detect ships, which later led to the development of RADAR technology. Tesla's innovative thinking and inventions earned him worldwide fame, and he left a lasting impact on the field of electricity and power generation.
