Hint: A dielectric is a substance with low electrical conductivity that also has the capacity to retain electrical charge (due to Dielectric polarization). As a result, it exhibits only displacement current, making it suitable for use in the construction of a capacitor to store and return electrical energy.
Complete step by step solution:
A material's relative permittivity, also known as its dielectric constant, is its (absolute) permittivity stated as a ratio to the vacuum permittivity.
Permittivity is a characteristic of a substance that influences the Coulomb force between two point charges within it. The electric field between the charges is reduced by relative permittivity as compared to vacuum.
Similarly, relative permittivity is the ratio of a capacitor's capacitance with that material as a dielectric to a similar capacitor with vacuum as a dielectric. The dielectric constant is another name for relative permittivity.
As a result, the dielectric constant's value is critical in the construction of many electronic components.
The dielectric constant of water is quite high. Water has a dielectric constant that is higher than any other material. A high dielectric constant indicates the solvent's ability to filter charges. It means that water molecules will surround both anions and cations in a solution, reducing the attraction between them. The ratio of the substance's permittivity to the permittivity of empty space is the dielectric constant of a material. Because it is the ratio of two comparable things, it is a unitless, dimensionless quantity.
Note:
The distinction between active and passive dielectrics is that active dielectrics are those that adapt easily to the storage of electrical energy, whilst passive dielectrics are those that restrict the storage of electrical energy.
Glass is an example of a passive dielectric, whereas piezoelectric is an example of an active dielectric.
