Leyden Jar
Its invention was a discovery made independently by German cleric Ewald Georg von Kleist on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek of Leiden (Leyden) in 1745–1746.[3] The invention was named after the city. -
Linked Glass Battery
These capacitors were charged with a static generator and discharged by touching metal to their electrode. Linking them together in a "battery" gave a stronger discharge. Originally having the generic meaning of "a group of two or more similar objects functioning together", as in an artillery battery, the term came to be used for voltaic piles and similar devices in which many electrochemical cells were connected together in the manner of Franklin's capacitors. -
Through Battery
Cruickshank solved this problem by laying the battery on its side in a rectangular box. The inside of this box was lined with shellac for insulation, and pairs of welded-together zinc and copper plates were laid out in this box, evenly spaced. The spaces between the plates were filled with dilute sulphuric acid. So long as the box was not knocked about, there was no risk of electrolyte spillage. -
Animal Electricity
When he touched its leg with his iron scalpel the leg twitched. Galvani believed the energy that drove this contraction came from the leg itself and called it animal electricity.The effect was named after the scientist Luigi Galvani, who investigated the effect of electricity on dissected animals in the 1780 and 1790. In 1786, he discovered that, when a frog's legs are touched by both a copper probe and a piece of iron at the same time they then twitch just as if an electric current were present -
Voltaic Battery
It was invented by Alessandro Volta, who published his experiments in 1799. The voltaic pile then enabled a rapid series of other discoveries including the electrical decomposition of water into oxygen and hydrogen by William Nicholson and Anthony Carlisle and the discovery or isolation of the chemical elements: sodium potassium calcium boron barium strontium and magnesium by Humphry Davy.He reported the results in 1800. -
Volta Battery
Batteries provided the main source of electricity before the development of electric generators and electrical grids around the end of the 19th century. Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers, mobile phones, electric cars, and many other electrical devices. -
Daniell Cell Battery
The Daniell cell is a type of electrochemical cell invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulphuric acid and a zinc electrode. He was searching for a way to eliminate the hydrogen bubble problem found in the voltaic pile, and his solution was to use a second electrolyte to consume the hydrogen produced by the first. -
Porous Pot Cell Battery
The porous pot version of the Daniell cell was invented by John Dancer, a Liverpool instrument maker, in 1838. It consists of a central zinc anode dipped into a porous earthenware pot containing a zinc sulfate solution. The porous pot is, in turn, immersed in a solution of copper sulfate contained in a copper can, which acts as the cell's cathode. The use of a porous barrier allows ions to pass through but keeps the solutions from mixing. -
