Usage examples of "potential difference".
This field possesses different 'potentials' at its various points and so there exists a certain potential difference between the two electric charges.
Using that number, you can calculate the gravitational potential difference between the ground and a point 1 meter higher.
Some people have a potential difference in the opposite direction and are in such need of positive energy, someone else's electricity, that they seem to suck all the energy out of that person and into them.
One electron-volt is the energy gained by a single electron accelerated through a potential difference of 1 volt.

We will do another run and calibrate this white noise with a possible transient potential difference.
Gradually the potential difference evened out and the lightning disappeared.
There is a great potential difference between that and your actual physical form.
Whether the energy comes from fuel or a waterfall or goetic quantum-wave transference across a potential difference, or whatever, it's conserved, same as mass is conserved in a transformation.
It's like powerfluxes-the greater the potential difference and the better the balance .
He knew that when the circle was spinning fast enough against the standing magical field of the Discworld itself in its slow turning, the resulting astral friction would build up a vast potential difference which would earth itself in a vast discharge of the Elemental Magical Force.
He knew that when the circle was spinning fast enough against the standing magical field of the Discworld itself in its slow turning, the resulting astral friction would build up a vast potential difference which would earth itself in a vast discharge of the Elemental Magical Force, the circle was a blur now, and the walls of the Tree rang with the echoes of the chant Rincewind felt the familiar sticky prickling in the scalp that indicated the build-up of a heavy charge of raw enchantment in the vicinity, and so he was not utterly amazed when, a few seconds later, a shaft of vivid octarine light speared down from the invisible ceiling and focused, crackling, in the centre of the circle.
