The SI-derived unit of electric potential, named after Italian physicist Alessandro Volta. 1 volt = 1 joule per coulomb, representing electric potential difference or electromotive force. Used to describe batteries (e.g., AA battery: 1.5 V), household outlets (220 V in China), and electronic circuit power supplies. Universally adopted and a core electrical unit in China’s legal metrology system.
