do you have an original graphic we could add here, relating to 'potential difference'? please see the main Gridbuilding page for details of how to get in touch




The potential difference between two points in an electrical circuit is a measure of the energy change when a unit charge moves from one to the other.


Potential difference can, therefore, be thought of a bit like a gradient: the steeper the hill, the more energy a ball will have as it moves down the hill.


Potential difference is measured in volts (V). There is an energy change of one joule if one coulomb of charge moves through a potential difference of one volt.


The Earth is used as a reference point and given a potential of zero.
