What You'll Learn
The first electrical experiments
The first observation of electricity dates back to 500 BC, when Thales of Miletus discovered static electricity by rubbing fur on amber. However, electricity remained an intellectual curiosity for millennia. In the 1600s, the English scientist and physician William Gilbert wrote 'De Magnete', in which he studied electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the term 'electricus' ("of amber" or "like amber"), which gave rise to the English words "electric" and "electricity".
In the early 1700s, English scientist Francis Hauksbee made a glass ball that glowed when rubbed, demonstrating electrical attraction and repulsion. This discovery would eventually lead to neon lighting. In 1775, Hugh Williamson reported a series of experiments on the electric eel to the Royal Society, and the same year, John Hunter described the structure of the fish's electric organs. In 1791, Luigi Galvani discovered bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to muscles.
In 1800, Alessandro Volta invented the first true battery, providing scientists with a more reliable source of electrical energy. In 1819-1820, Hans Christian Ørsted and André-Marie Ampère recognised electromagnetism, the unity of electric and magnetic phenomena. In 1821, Michael Faraday invented the electric motor, and in 1831, he invented the first electrical generator, converting mechanical energy into electrical energy. In 1879, Thomas Edison patented the first practical incandescent lightbulb, which could burn for more than 1200 hours.

Early electrical energy use
The use of electrical energy has a long history, dating back to ancient civilizations. Early electrical energy use was primarily focused on understanding and harnessing the power of electricity, which was largely an intellectual curiosity for millennia.
One of the earliest known uses of electricity was by the Greeks, Romans, and Egyptians, who reportedly used electric fish as a treatment for medical conditions such as epilepsy and gout. In 500 B.C., Thales of Miletus, a Greek philosopher, discovered static electricity by rubbing fur on amber and observing that it attracted small objects. However, he incorrectly attributed this phenomenon to magnetism.
In the 1600s, English scientist William Gilbert made significant contributions to the study of electricity by distinguishing between the lodestone effect and static electricity produced by rubbing amber. He coined the term "electricus" from the Greek word for amber, which eventually led to the modern usage of the word "electricity". During this time, Isaac Newton also made early investigations into electricity, with ideas written down in his book Opticks, which some argue is the beginning of the field theory of the electric force.
In the 1700s, English scientist Francis Hauksbee created a glass ball that glowed when rubbed, demonstrating electrical attraction and repulsion. This discovery would later lead to neon lighting. In 1752, Benjamin Franklin conducted his famous kite experiment, proving that lightning was a form of electrical energy.
The late 1700s and early 1800s saw further advancements in the understanding and application of electrical energy. In 1775, Hugh Williamson reported experiments on the electric eel's shocks to the Royal Society, while John Hunter described the structure of the fish's electric organs. Luigi Galvani's discovery of bioelectromagnetics in 1791 demonstrated the role of electricity in neuron signalling to muscles. Alessandro Volta's battery, or voltaic pile, introduced in 1800, provided scientists with a more reliable source of electrical energy compared to previous electrostatic machines.

The electric light
The history of electric lighting is a fascinating one, with many pioneers contributing to its development over the centuries. The first documentation of electricity dates back to around 500 BC when Thales of Miletus, a Greek philosopher, discovered static electricity by rubbing fur on amber. However, it wasn't until the 1600s that English physician and physicist William Gilbert published the first theories about electricity in his book, 'De Magnete'.
In the early 1700s, English scientist Francis Hauksbee made a significant contribution to the development of electric lighting. He created a glass ball that glowed when rubbed, demonstrating the principles of electrical attraction and repulsion. This discovery would eventually lead to neon lighting centuries later.
In the 1800s, several inventors and scientists made breakthroughs that advanced the field of electric lighting. Alessandro Volta's battery, or voltaic pile, provided scientists with a more reliable source of electrical energy. This was followed by Hans Christian Ørsted and André-Marie Ampère's recognition of electromagnetism in 1819-1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm analysed the electrical circuit mathematically in 1827.
However, it was Thomas Edison who is widely credited with pioneering the incandescent light bulb. He opened the first power plant in New York City in 1882 and installed the first electric streetlights in Roselle, New Jersey, marking the transition from gas lighting to electric lighting in American cities. Edison's companies eventually evolved into the General Electric brand, known for its electric light bulbs, among other innovations.
It is worth noting that Edison's work built upon existing technologies, and he was not without rivals. Nikola Tesla, who worked at the French branch of Edison's company before branching out on his own, developed an alternating current (AC) system that competed with Edison's direct current (DC) power system. This rivalry, known as the War of the Currents, led to significant advancements in electrical engineering, such as powering Buffalo, New York, with energy from Niagara Falls.
