Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.

II Review | Constants | Periodic Table
The dielectric in a capacitor serves two purposes. It increases the
capacitance, compared to an otherwise identical capacitor with an air
gap, and it increases the maximum potential difference the capacitor
can support. If the electric field in a material is sufficiently strong, the
material will suddenly become able to conduct, creating a spark. The
critical field strength, at which breakdown occurs, is 3.0 MV/m for
air, but 60 MV/m for Teflon.
