Phenolic resin dielectric constant
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.
