1800 (report of the pile) / Europe
Volta’s pile supplies a sustained electric current
Alternating metal plates and wet separators supplied a current that could last beyond a brief electrostatic discharge.

The story
In a letter to Royal Society president Joseph Banks, Volta described a pile made from repeated metal-and-electrolyte units. It emerged from debates involving Galvani and others. Volta emphasized metallic contact, rather than providing today’s complete electrochemical explanation. Early piles also suffered polarization and other limitations: sustained operation did not mean an indefinitely constant current.
Connections and context
A usable current source supported electrolysis, Ørsted’s magnetic experiments and later circuit research, showing how new apparatus changes available questions.
