Electric Potential Energy Calculator

The Electric Potential Energy Calculator will calculate the:

  1. Electric potential energy of a point test charge at a given distance from another point charge (electric potential energy inside a non-uniform field)
  2. Electric potential energy of a point test charge at a given distance from a zero-potential position (electric potential energy inside a uniform field)

Please note that in the Electric Potential Energy Calculator, Medium is considered as homogenous.
