The change in potential energy per unit charge between two points in an electric field is:
Correct answer: B. Potential difference
- A. Retentivity
- B. Potential difference
- C. Intensity
- D. Permittivity
- E. Permeability
Explanation
Potential difference, also known as voltage, is the difference in electric potential energy between two points in an electric field. It represents the work needed to move a unit charge from one point to another and is a measure of the driving force that pushes electric charges through a circuit.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
