is the potential difference more basic or potential
Answers
If the question means which is more basic, potential or potential difference - the answer is "Electric Potential is more basic than potential difference."
Electric potential is a location-dependent quantity that expresses the amount of potential energy per unit of charge at a specified location. When a Coulomb of charge (or any given amount of charge) possesses a relatively large quantity of potential energy at a given location, then that location is said to be a location of high electric potential. And similarly, if a Coulomb of charge (or any given amount of charge) possesses a relatively small quantity of potential energy at a given location, then that location is said to be a location of low electric potential.
The potential difference is the difference in electric potential between two points per unit electric charge. The voltage between two points is equal to the work done per unit of the charge against a static electric field to move the test charge between two points.
The electrical potential Φ refers to a quantity with some numeric value. It is usually dependent on space and time Φ (x⇒,t), so it's a field where for every place and the moment you get a number. By potential difference ΔΦ, one denotes the difference between two such values taken at different positions.
