How does electric potential change as distance from a positive charge increases?

The electric potential generated by a positive charge is a scalar quantity that is inversely proportional to the distance from that charge.1

As the distance from a positive charge increases, the electric potential decreases. Mathematically, if you define the potential to be zero at an infinite distance from the charge, the potential at any point is highest near the charge and drops toward zero as you move further away. This relationship reflects the fact that a positive test charge experiences a repulsive force from the source charge; moving the test charge further away requires less work against this electric field, corresponding to a lower potential.12
