Electrostatic potential due to point charge
===========================================

Electrostatic potential of electric field due to a point charge is inversely proportional
to the distance to the point charge. Also see :doc:`laws.electricity.electrostatic_potential_is_work_to_bring_from_reference_point_over_charge`.
