The electric potential difference between two points in an electric field is defined as being numerically equal to the work done in moving a unit charge between the two points. The units or dimensions of potential difference are (work)/(charge), which is N m/C or volt. The units of ...
Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Electric potential is measured in joules per coulomb (i.e., volts), and differences in potential are measured with a
