Define $1$ volt.
(N/A) The potential difference between two points in a current-carrying conductor is said to be $1$ volt when $1$ joule of work is done to move a charge of $1$ coulomb from one point to the other.
Mathematically,$V = W / Q$,where $V = 1$ volt,$W = 1$ joule,and $Q = 1$ coulomb.
Mathematically,$V = W / Q$,where $V = 1$ volt,$W = 1$ joule,and $Q = 1$ coulomb.
