Voltaic Pile
The Voltaic Pile (pronounced: vohl-tay-ik pahyl) is a historical piece of scientific equipment that played a significant role in the development of the field of Electrochemistry.
Etymology
The term "Voltaic Pile" is derived from the name of its inventor, Alessandro Volta, an Italian physicist, and the word "pile", which in this context refers to a stack or series of objects.
Definition
A Voltaic Pile is an early form of battery that produces an electric current. It was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Alessandro Volta in 1800.
Construction
The Voltaic Pile is constructed from a series of discs of two different metals, commonly zinc and copper, separated by cloth or cardboard soaked in brine (a solution of salt in water), which serves as the Electrolyte. This arrangement of alternating different metals and electrolyte creates a series of galvanic cells in a stack, hence the name "pile".
