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.

Question

**Dielectric in Capacitors**

The dielectric in a capacitor serves two purposes:

1. It increases the capacitance compared to an otherwise identical capacitor with an air gap.
2. 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 conductive, creating a spark. The critical field strength, at which breakdown occurs, is 3.0 MV/m for air, and 60 MV/m for Teflon.
