What You'll Learn
The earliest studies of electricity
The study of electricity began as early as 500 B.C. when the Greek philosopher Thales of Miletus discovered static electricity by rubbing fur on amber. However, he incorrectly believed that the attraction was due to a magnetic effect. 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 this work, Gilbert made a careful study of electricity and magnetism, distinguishing between the lodestone effect and static electricity produced by rubbing amber. He coined the Neo-Latin word "electricus" ("of amber" or "like amber") to describe the property of attracting small objects after being rubbed.
The next significant contribution to the study of electricity came in the late 1700s with the experiments of English scientist Francis Hauksbee. He created a glass ball that glowed when rubbed, demonstrating electrical attraction and repulsion. This discovery would eventually lead to the development of neon lighting centuries later. Around the same time, in 1745, the Leyden jar, an early capacitor that could store electrical charge, was discovered by German and Dutch scientists. This invention marked one of the first attempts to create a device that used electricity.
In the 1800s, several inventors and scientists made significant advancements in the understanding and application of electricity. Benjamin Franklin's famous kite experiment in 1752 and Alessandro Volta's invention of the battery in 1800 expedited the process of harnessing electricity. Nicholson and Carlisle discovered that water could be decomposed by the current from a voltaic pile in 1800, a process now known as electrolysis. Their work was later expanded upon by Michael Faraday in 1833.
During this period, the focus was also on using electricity to power various devices. In 1832, Frenchman Hippolyte Pixii invented a machine that generated alternating current, which flowed in one direction and then the opposite. This machine demonstrated the basic idea of electromagnetic induction, using magnets to create a flow of current in wires. Belgian Floris Nollet improved upon Pixii's design around 1850, and his generator was capable of producing approximately 50 volts. These generators were the first to be mass-produced by a manufacturing firm, marking the beginning of the Electrical Age.

The first devices to use electricity
While electricity is a natural phenomenon that has always existed, humans began harnessing its power in the 18th century. The first devices to use electricity were invented during this period of exploration and experimentation.
One of the earliest known devices to store electrical charge was the Leyden jar, discovered in the 1740s by German and Dutch scientists. This invention was soon followed by the creation of light bulbs, generators, and electric panels, which revolutionized modern life.
In the 1800s, inventors began experimenting with electromagnetism and its potential to power machines. American Joseph Henry, for instance, built a powerful electromagnet using a large battery in 1829. This invention was more than just a scientific instrument; it could lift hundreds of pounds of metal, showcasing the practical applications of electricity.
Another early device that utilized electricity was the telegraph, which became a breakthrough form of communication in the 19th century. This new technology brought electricity into the public eye and marked the beginning of the Electrical Age.
Additionally, doctors in Geneva started treating patients with electric shocks as early as 1745, just a few years after the invention of the Leyden jar. This practice, known as "electrotherapy," was believed to cure ailments and continued to be explored into the early 20th century.

The development of electrical systems
While electricity was not invented, as it has always existed in nature, the development of electrical systems as we know them today was pioneered by several key figures. The first documentation of electricity dates back to 500 B.C. when Thales of Miletus 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 experimented with electrical attraction and repulsion, creating a glowing glass ball that could be used for reading. This discovery would eventually lead to neon lighting.
The exploration of electricity continued to advance in the 18th century, with notable contributions from Benjamin Franklin, who conducted his famous kite experiment in 1752, and Alessandro Volta, who invented the battery in 1800. These developments laid the foundation for further innovations in electrical systems.
In the 19th century, electricity began to power homes, businesses, and streetlights. Thomas Edison played a significant role in this era, perfecting the light bulb and establishing a central generating station at Pearl Street in lower Manhattan in 1882. Around the same time, advances in alternating-current (AC) technology opened up new possibilities for power generation, including hydropower.
The work of Michael Faraday, a British scientist, is also worth mentioning. Faraday, along with Ampère, demonstrated the relationship between electric and magnetic fields, showing that a time-varying magnetic field creates an electric field and vice versa. These variations are known as electromagnetic waves, which were later analysed theoretically by James Clerk Maxwell in 1864.

The use of electricity in medicine
While electricity was not invented, as it has always existed in nature, humans began harnessing it in the 18th century. The use of electricity in medicine, also known as electrotherapy, dates back to ancient Egypt and Rome, where the electric torpedo fish was used to treat pain, gout, and epilepsy. The first recorded treatment of a patient using electricity was by Johann Gottlob Krüger in 1743. However, it was rejected by mainstream medicine. Over the years, several pioneers have contributed to the development of applications for electricity in medicine, and today, there are numerous uses of electricity in the medical field.
French neurologist Guillaume Benjamin Armand Duchenne (1806-1874) made significant discoveries by applying electric current to a patient's skin. He found that muscles contracted when an electric current was applied and developed an induction coil to apply electricity to muscles for diagnosis and later expanded the device for therapeutic use. Duchenne is also credited with being the first to use an "artificial pacemaker" by using an electrical current to induce electrophrenic stimulation to resuscitate a drowned girl.
In the early 20th century, Jacques–Arsene D’Arsonval's discovery that high-alternating current could be applied to tissues to control bleeding without affecting sensory nerves or causing muscular contractions revolutionized medicine. This technology was soon used to treat skin lesions, bladder tumors, and hemorrhoids, leading to the development of electrosurgery.
Today, electrotherapy is used in medicine to treat a range of conditions. Bioelectronic devices are approved to treat migraines, cardiac arrhythmias, obsessive-compulsive disorder, depression, chronic pain, stroke, and more. Additionally, electrotherapy is used in physical therapy and neurotherapy to change neuronal activity and speed up wound healing. Researchers are also studying how electricity can be used to treat wounds and diabetes.
While the use of electricity in medicine has faced challenges, such as negative perceptions during World War II due to its association with Nazi experimentation, and the lack of consistent understanding of optimal stimulation parameters, it continues to advance and evolve. The development of electroceuticals and bioelectronic medicine shows promising potential for transforming medical practices and treating a variety of conditions.

The electrical age
However, the start of the Electrical Age is often associated with Thomas Edison, who began providing electricity to a portion of New York City on September 4, 1882. Edison developed six 27-ton constant-voltage dynamos, each capable of supplying about 1,200 lamps. He also installed 80,000 feet of underground conductors. This event, now considered monumental, was largely uncelebrated at the time. Within a year, the system expanded to 10,000 lamps serving 513 customers.
Edison is also credited with perfecting the light bulb, though other inventors like Humphry Davy and Joseph Swan contributed to its development. Early uses of electricity included light bulbs, telegraphs, and early batteries. By the late 19th century, electricity powered homes, businesses, and streetlights.
