The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. [1] It was invented by Italian chemist Alessandro Volta , who published his experiments in 1799. [ 2 ]

The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth or cardboard soaked in brine (i.e., the electrolyte). Unlike the Leyden jar, the voltaic pile produced continuous electricity and stable current, and lost little charge over time when not in use, though his early models could ...
Schema of the classical Hall effect discovered in 1879, where a voltage is created perpendicular to the current in a circuit due to the influence of a magnetic field. 1800 – The Voltaic pile, the first electric battery is developed by Alessandro Volta. [21]
The trough battery was a variant of Alessandro Volta's voltaic pile and was designed by the Scottish professor of chemistry William Cruickshank in 1800. [1]
A simple electromagnet, consisting of an insulated wire wound around an iron core. An electric current passing through the wire creates a Magnetic field, with a north pole at one end and a south pole at the other. The first application of electricity that was put to practical use was electromagnetism. [18]
The magnet exerted a tangential force on the wire, making it circle around the magnet for as long as the current was maintained. ... The voltaic pile, and its modern ...
Voltaic pile (1796): Alessandro Volta constructs a new source of electricity, the electrical battery. Cavendish experiment (1798): Henry Cavendish's torsion bar experiment measures the force of gravity in a laboratory. Double-slit experiment (c.1805): Thomas Young shows that light is a wave in his double-slit experiment.
