Electricity Timeline

Ancient Egyptian texts described electric fish and identified them with thunder[3]

2750 BCE

The electric catfish of the Nile was well known to the ancient Egyptians.[8] The Egyptians reputedly used the electric shock from them when treating arthritis pain.[9] They would use only smaller fish, as a large fish may generate an electric shock from 300 to 400 volts.

English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand

1705

, Hauksbee had discovered that if he placed a small amount of mercury in the glass of his modified version of Otto von Guericke's generator, evacuated the air from it to create a mild vacuum and rubbed the ball in order to build up a charge, a glow was visible if he placed his hand on the outside of the ball. This remarkable discovery was unprecedented at the time. This glow was bright enough to read by. It seemed to be similar

German physicist Ewald Georg

1745

German physicist Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek invented Leyden jars

Luigi Galvani

1780

talian scientist Luigi Galvani discovered the Galvanic action in living tissue

Charles-Augustin de Coulomb fo

1785

French physicist Charles-Augustin de Coulomb formulated and published Coulomb's law in his paper Premier Mémoire sur l’Électricité et le Magnétisme

Laplace transform

1785

French mathematician Pierre-Simon Laplace developed the Laplace transform to transform a linear differential equation to an algebraic equation. Later, his transform became a tool in circuit analysis.

Alessandro Volta

1820

One week after Ørsted's discovery, French physicist André-Marie Ampère published his law. He also proposed right-hand screw rule

law of induction

1831

English physicist Michael Faraday published the law of induction (Joseph Henry developed the same law independently)

Wheatstone bridge

1833

Edith Clarke invents the "Clarke calculator"

1892

Edith Clarke invents the "Clarke calculator", a graphical calculator for solving line equations involving hyperbolic function, allowing electrical engineers to simplify calculations for inductance and capacity in power transmission lines[9
