electric potential is to electricity what temperature is to heat, or pressure is to any medium of different densities.
This flow is said to be due to a difference of electric potential between the two conductors.
There is thus a more or less permanent or resting difference of electric potential between them.
A transverse difference of electric potential (Hall effect).
As this process of alternating the electric potential is repeated, the ions gain speed and energy with each revolution.
A transverse difference of electric potential (Nernst effect).
In this way a steady fall of electric potential is set up along the length of the tube.
It does not light because in the middle both halves of the coil neutralize each other, and the electric potential is zero.

A measure of the work required by an electric field to move electric charges. Its unit is the volt. Also called voltage. See more at Ohm's law.
