What is the difference between electric potential and potential difference?
Potential Difference. Potential difference , or voltage, is the difference in electric potential energy between two points. It is denoted by ∆V and has units of volts, or joules per Coulomb.
Potential is the specific potential energy. That is, when potential energy depends on some quantity associated with object in question, potential is potential energy per unit of that quantity. For example, gravitational potential is gravitational potential energy per unit of mass. Electrostatic potential is the electrostatic potential energy per unit of charge.
Attraction or repulsion whereas Electric potential difference between two points in an Electric field is defined as the amount of work done in moving unit positive charge from one point to another point against the electric force.
