This page provides an explanation to determine the sign of potential difference in which the sign shows whether energy is lost or gained by a moving charged particle.
The Main Idea
By determining the direction of path relative to the direction of electric field, the sign of potential difference can then be determined. The sign of potential difference then shows if there is an increase or a decrease in potential energy, as well as kinetic energy.
A Mathematical Model
Potential difference is the product of the electric field [math]\displaystyle{ \Delta E }[/math] and the relative path [math]\displaystyle{ \Delta x }[/math].
