In the Pile that Volta described in 1800, a disk of copper is placed at the bottom, followed by a disk of cloth soaked in brine or acidulated water, followed by a disk ... The voltaic pile at the left, in the collection at Dartmouth College in Hannover, New Hampshire, is unusual in its provision of a built-in spark gap.

You can create your own voltaic pile using coins and paper towels. Mix salt with water (as much salt as the water will hold) and soak the paper towel in this brine. Then create a pile by alternating pennies and nickels.

The voltaic pile, which we now recognize under the name of "electrical battery," produced an immediate sensation and revived the lagging research in electricity. Within a short time, scientific apparatus houses were offering Volta's piles as regular items of equipment for research and demonstrations.

A Voltaic Pile (c. 1800) ... This voltaic pile consists of thirty metal disks separated by layers of (dampened) cloth. During the first part of the nineteenth century large voltaic piles were constructed to provide sources of continuous current.

Most historians attribute the invention of the battery to Alessandro Volta since his voltaic pile was the first battery that produced a reliable, steady current of electricity. Volta’s invention was to give rise to electrochemistry, electromagnetism and the modern applications ... Repeat the Voltaic Pile Experiment...

Q2 Also, if voltage = current*resistance, then shouldn't it be that the more layers in the pile, the higher the voltage? A2The voltage increases with each layer you add, but this is not because voltage = current * resistance.

In 1800, Alessandro Volta of Italy built the voltaic pile and discovered the first practical method of generating electricity. Count Volta also made discoveries in electrostatics, meteorology and pneumatics. His most famous invention, however, is the first battery.
