A high dielectric constant is not necessarily desirable. Generally, substances with high dielectric constants break down more easily when subjected to intenseelectric fieldscompared to materials with low dielectric constants (see Figure 1). Dielectric materials Adielectric materialhas weak electricalconductivi...
with a high dielectric constant will have a high refractive index, which means it can bend light more than a material with a low dielectric constant. Additionally, the dielectric constant is used in manysensing applications, such as in capacitive sensors, dielectric spectroscopy and permittivity ...
Where is the relative electrical permittivity. It is also called as dielectric constant of the separation medium between charges, and is denoted by k. As a result of eq 1.6 it is clear that the dielectric constant of the medium is the ratio of the absolute electrical permittivity of vaccum ...
It is also known as Relative permittivity.If two charges q1and q2are separated from each other by a small distance r. Then by using the coulombs law of forces the equation formed will be ——— 2.6 In the above equation is the electrical permittivity or you can say it, Dielectric const...
