`DeltaPE_("elec") = q * Deltav `

Enter a value for all fields

The **difference in voltage between two points in space** is defined as `DeltaPE_"elec"=qDeltaV`, 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
- `DeltaV` = change in voltage
