The electrical unit known as the volt is named in honor of the Italian physicist Alessandro Volta to recognize his foundational contributions to the study of electricity.

In 1800, Volta invented the voltaic pile, which was the first battery capable of providing a continuous source of electric current. This invention proved that electricity could be generated through chemical means rather than relying on "animal electricity," as previously theorized by Luigi Galvani. By demonstrating that a steady flow of current could be produced using alternating metal disks, Volta effectively launched the field of electrochemistry.1

Because his work provided the essential understanding of electromotive force—the pressure that drives electric current—the unit for measuring this potential difference was named the volt in 1881.12
