Within a highly porous fibrous structure, the intimate surface of contact between the capacitor plates and the paper is very low therefore, it is often used in the form of cardboard impregnated with mineral oil [1] indeed, paper has a low dielectric constant (between 1 and 25) with respect to pure cellulose (6. A dielectric is a substance in which an electric field may be maintained with zero or near-zero power dissipation a dielectric material is an electrical insulator in a dielectric, electrons are bound to atoms and molecules hence there are few free electrons the dielectric strength of a material is an intrinsic property of the bulk. Full-text paper (pdf): determining dielectric constants using a parallel plate capacitor. However, this experiment consistently results in a nonlinear relation between capacitance and inverse dielectric thickness and yields dielectric constants that are much too low pre- dominantly because of air trapped between the layers of the dielectric many instructors choose paper as the dielectric material paper has the.

The charging potential decreases and the electrical conductivity, potential decay rate, and dielectric constant of paper increase with increasing temperature the dependencies are exponential and the temperature dependencies and their activation energies are altered by the ion content the results have been utilized in. Permittivity and dielectric constant are two terms that are central to capacitor technology often talk will be heard of capacitors with different dielectrics being used electrolytic, ceramic, paper, tantalum and all the common names for capacitors refer to the dielectric material that is used the dielectric material provides the. Character of the dielectric material (called dielectric constant,ε ) with the capacitance is a simple, ie d a c r 0 εε = hence several experiments are being done to determine the dielectric constant of a solid dielectric [1, 2 3, 4, 5, 6 , 7, 8, 9, 10] most of these use thin sheet/s of paper as the dielectric material.
