Electric Potential of a Point Charge
Let’s contemplate a scenario where a point charge ‘q’ exists alongside another charge ‘Q’, with an infinite distance separating them.
UE (r) = ke × [qQ/r]
where, ke = 1/4πεo = Columb’s constant
Let us consider a point charge ‘q’ in the presence of several point charges Qi with infinite separation between them.
UE (r) = ke q × ∑ni = 1 [Qi /ri]

Electric Potential Energy
Electrical potential energy is the cumulative effect of the position and configuration of a charged object and its neighboring charges. The electric potential energy of a charged object governs its motion in the local electric field.
Sometimes electrical potential energy is confused with electric potential, however, the electric potential at a specific point in an electric field is the amount of work required to transport a unit charge from a reference point to that specific point and electrical potential energy is the amount of energy required to move a charge against the electric field.
In this article, let’s understand the electrical potential energy, electric potential, their key concepts, applications, and solved problems.
