What is Electrostatic Potential and Capacitance?

Electrostatic potential is the work done in bringing a unit positive charge from infinity to a point in an electric field. Capacitance, on the other hand, is the ability of a system to store charge per unit potential difference. It is determined by the physical characteristics of the system, such as geometry and material properties.
