The discovery of electricity is credited to several individuals who made significant contributions to its study over the centuries. One of the earliest known experiments with electricity was conducted by the Greek philosopher Thales of Miletus, who discovered the effects of magnetism and static electricity by rubbing amber with animal fur. In 1600, English scientist William Gilbert coined the term electricus to refer to the property of attracting small objects after being rubbed, and this term was later modified to electricity by polymath Sir Thomas Browne in 1646. German scientist Otto von Guericke built upon this work by successfully producing static electricity through the rotation of a ball of sulfur.

Benjamin Franklin's kite experiment
While electricity was already a known phenomenon in the mid-18th century, Benjamin Franklin is credited with discovering how to measure it. He is known for his kite experiment, which aimed to investigate the nature of lightning and electricity, which were not yet fully understood at the time.
Franklin's kite experiment was first proposed and conducted in 1752, with the assistance of his son, William. The experiment took place during a thunderstorm, with Franklin flying a kite made with a large silk handkerchief, a hemp string, and a silk string. A sharp wire, acting as a lightning rod, was attached to the top of the kite, and a metal key was attached to the hemp string. The hemp string, wet from the rain, would conduct an electrical charge quickly, while the silk string, held by Franklin and his son in the doorway of a shed, remained dry and acted as an insulator.
As the kite flew near thunderclouds, it collected static electricity from the air and conducted it down the wet kite string to the ground. Franklin observed that the loose threads of the hemp string stood erect, attracted by an approaching finger, demonstrating the electrical charge. This experiment helped prove that lightning was a form of electricity, and that it could be harnessed for further experiments and to protect tall buildings from damage.
Franklin described his experiment in the Pennsylvania Gazette on October 19, 1752, without explicitly stating that he had performed it himself. The account was read to the Royal Society and published in the Philosophical Transactions. While some have questioned whether the experiment took place as described or at all, it remains a significant contribution to the understanding of electricity and lightning.

Volta's battery
The Voltaic pile, also known as the Voltaic cell, was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Italian chemist Alessandro Volta in 1799, although his work on the battery began in the late 18th century. The battery consisted of two plates of different metals immersed in a chemical solution.
The battery was the first device that produced electricity by joining two metals separated by a conductive liquid. This enabled the generation of a continuous electric current, allowing for the storage and delivery of electrical energy. This was a pivotal development in the field of electricity, laying the groundwork for future technological innovations.
The importance of this finding lies in the possibility of generating and storing energy artificially, which enabled the subsequent development of research into and the application of electricity. Volta was also the first to discover the chemical reaction that occurs when two different metals are joined. This reaction is known as the "Volta effect" and was instrumental in the development of electricity.
The Voltaic pile stimulated so much scientific inquiry that, by 1831, when Michael Faraday built the first dynamo, the basic principles of electricity had been established.

Faraday's electromagnetic induction
Michael Faraday, a British scientist and physicist, discovered the principle of electromagnetic induction in 1831. This discovery is considered one of the cornerstones of modern electromagnetism.
Faraday's law of electromagnetic induction, also known as Faraday's law, is the basic law of electromagnetism that helps predict how a magnetic field interacts with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction.
Faraday's law consists of two laws. The first law describes the induction of EMF in a conductor, stating that whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. If the conductor circuit is closed, a current is induced, known as the induced current. The second law quantifies the EMF produced in the conductor, stating that the induced EMF in a coil is equal to the rate of change of flux linkage.
Faraday performed three main experiments to discover the phenomenon of electromagnetic induction. In one experiment, he wrapped two coils of wire around opposite sides of an iron ring, forming a primitive toroidal transformer. When he connected one coil to a battery, he observed a brief deflection in a galvanometer attached to the second coil. He concluded that a changing current in the first coil created a changing magnetic field in the ring, which induced a current in the second coil.
Faraday's work on electromagnetic induction led to significant advancements in the field of electricity. He invented the first electrical generator in 1831, converting mechanical energy into electrical energy. Although his generator, known as Faraday's disc, was inefficient, it demonstrated the possibility of generating electric power using magnetism.

Hertha Ayrton's electric arc research
The English electrical engineer, mathematician, physicist, and inventor Hertha Ayrton (1854-1923) was one of the first women to make a significant contribution to scientific research, with a focus on the field of electricity. She studied physics, chemistry, and mathematics at Girton College, Cambridge University, becoming the first woman to obtain a degree at the university.
Hertha Ayrton's research on electric arcs, which she began in 1893, was of substantial commercial and industrial importance. Direct current arcs were widely used for lighting at the time, but arc lamps were plagued with problems. They hissed, sputtered, hummed, and rotated, producing unsteady illumination in a changing array of colours. Ayrton discovered that these phenomena were caused by the undulatory nature of the electric arc, which occurred when oxygen came into contact with the carbon rods used to create the arc. She also determined the relations among power supplied, potential across the arc, current, and arc length.
Hertha Ayrton wrote a series of articles for the Electrician explaining her findings, and in 1899, she became the first woman to read her own paper before the Institution of Electrical Engineers (IEE). Her paper was titled "The Hissing of the Electric Arc". Ayrton was subsequently elected as the first female member of the IEE. In 1901, she had her paper "The Mechanism of the Electric Arc" read before the Royal Society by John Perry, and in 1902, she published "The Electric Arc", a summary of her research and work on the electric arc. Ayrton was awarded the Hughes Medal by the Royal Society in 1906 in honour of her research on electric arcs and ripple marks in sand and water, becoming the first woman to receive the award for a scientific work that was exclusively her own.

Thomas Edison's lightbulb
The English scientist William Gilbert is often credited with discovering how to measure electricity for the first time. In 1600, he wrote De Magnete, in which he studied electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber.
Thomas Alva Edison is one of the most well-known inventors of all time. Born in Ohio in 1847, Edison received most of his education at home, where he set up a laboratory in the basement of his family's home in Michigan. Edison's mother, Nancy, encouraged his interest in chemistry and electronics by providing him with books on the subjects.
Edison's career began as a news butcher, selling newspapers, candy, and vegetables on trains. He later worked as a telegraph operator, which 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 began working on a system of electrical illumination in 1878.
Edison's goal was to create a long-lasting incandescent lamp that could be used for indoor lighting, competing with gas and oil-based lighting. The lamp would consist of a filament housed in a glass vacuum bulb, requiring a high-resistance system that would use less electrical power than the existing arc lamps. By January 1879, Edison had created his first incandescent electric light, using a thin platinum filament in the glass vacuum bulb to delay the filament from melting. However, the lamp only burned for a few hours, and Edison had to test thousands of other materials to improve the bulb's longevity.
Edison's work on the incandescent lamp built upon the efforts of previous inventors, including British scientist Warren de la Rue, who created an efficient lightbulb using a coiled platinum filament in 1840, and Alessandro Volta, who demonstrated a glowing wire in 1800. Despite the contributions of these earlier inventors, Edison's improvements to the incandescent lamp and his development of a high-resistance system were significant steps towards creating small electric lights suitable for home use.
