Electric potential at a point is the amount of electric potential energy per unit charge at that point in an electric field. It is a scalar quantity that represents the work done in moving a unit positive charge from infinity to that point in the electric field.
Electric potential energy, on the other hand, is the energy stored in an electric field due to the position of charged particles. It is the work done in assembling a collection of charges in a particular configuration. The electric potential energy of a system of charges is directly related to the electric potential at each point in the system.

Electric Potential at a Point
Electric potential (V) at a point is a scalar quantity that represents the amount of electric potential energy (PE) per unit charge (q) at that point. It is measured in volts (V).
The electric potential at a point is given by the equation:
``` V = PE / q ```
where:
- V is the electric potential in volts (V) - PE is the electric potential energy in joules (J) - q is the electric charge in coulombs (C)
Electric Potential Energy
Electric potential energy is a type of energy that exists when two or more electrically charged objects are separated by a distance. It is the amount of work that would be required to move a charge from one point in an electric field to another point against the electric force.
The electric potential energy of a system of charges is given by the equation:
``` PE = k - (q1 - q2) / r ```
where:
- PE is the electric potential energy in joules (J) - k is Coulomb's constant (8.988 × 10^9 N m^2/C^2) - q1 and q2 are the charges of the objects in coulombs (C) - r is the distance between the objects in meters (m)
Relationship between Electric Potential and Potential Energy
Electric potential and electric potential energy are closely related. The electric potential at a point can be thought of as the amount of electrical work that would be done per unit charge on a test charge placed at that point.
The electric potential energy of a system of charges can be calculated from the electric potential at a point in the system by multiplying the potential by the charge of the object.
