Electric potential energy is the amount of potential energy a charged particle possesses due to its position in an electric field. The electric potential energy is a conservative force.

The formula for electric potential energy is:

• Definitions
  • is the electric potential energy, measured in Joule
  • is Coulomb's constant
  • and are the charges of the two particles interacting, measured in Coulomb
  • is the distance between the two particles, measured in meters

Examples
