How dielectric constant is going to measure

Question

Accepted Answer

The dielectric constant is measured by applying an electric field to a material and measuring the resulting polarization.

Dielectric constant is a measure of a material's ability to store electrical energy in an electric field.
It is determined by comparing the capacitance of a capacitor with the material as the dielectric to the capacitance of the same capacitor with a vacuum as the dielectric.
The dielectric constant is calculated as the ratio of the capacitance with the material as the dielectric to the capacitance with a vacuum as the dielectric.
It is typically measured using a device called a capacitance meter or a dielectric constant meter.
Examples of materials with high dielectric constants include water (80.4), ceramic materials (e.g. barium titanate with a dielectric constant of 1200), and certain polymers.
