`DeltaV = (DeltaPE_("elec"))/q`

Enter a value for all fields

The **difference in voltage between two points in space** is defined as `DeltaV=(DeltaPE_"elec")/q`, where:

- `DeltaPE_"elec"` is the change in the electrical energy of a particle
- `q` is the charge as it moves from the initial point to the final point
