Answer» Solution :a. No. Potential difference is a FIELD property. Potential energy is the interaction energy of charge configuration. b. The electrostatic potential at a point in an electric field is defined as the work done in bringing a unit positive charge from infinity to that point against the field. Electric potential difference between two points is equal to the work done in moving a unit test charge between them. The potential energy of a SYSTEM of charges is defined as the work done in bringing the charges from infinity to form the system. Potential energy, `"U =Potential difference " xx " Charge"` |
