What is the SI unit of electric potential difference, and who is it named after?

The SI unit of electric potential difference is the volt, represented by the symbol “V.” It is named after the Italian physicist Alessandro Volta, who invented the voltaic pile, the first chemical battery, in 1800. Volta’s work laid the foundation for understanding electrical potential difference. The volt is defined as one joule of energy per coulomb of charge, emphasizing the relationship between electric potential difference and the work done in moving electric charge. The unit honors Volta’s significant contributions to the field of electricity and electrochemistry.
