WebThe Dielectric Constant is a convenient way of discussing the permittivity of materials. Recall that the permittivity of a vacuum (that is, in outer space or where there is no atoms or material in a volume - also known as Free Space) is 8.854*10^-12 [Farads/meter]. Suppose the permittivity of a material such as FR4 is to be determined. WebThe dielectric constant formula is: Where: C = capacitance using the material as the dielectric capacitor C 0 = capacitance using vacuum as the dielectric ε 0 = Permittivity of free space (8.85 x 10 -12 F/m i.e. Farad per metre) A = Area of the plate/sample cross section area T = Thickness of the sample sharon lyons obituaryWebA common example of a dielectric is the electrically insulating material between the metallic plates of a capacitor.
