Sentences with dielectric constant
di·e·lec·tric con·stant
D d - Substances with a low dielectric constant include a perfect vacuum, dry air, and most pure, dry gases such as helium and nitrogen.The dielectric constant of a vacuum is defined as 1, that of air is very close to 1, and all other materials have values specified in relation to air or a vacuum.Dielectric constant is the ratio of the capacitance of a capacitor with the given material as dielectric, to the capacitance of the same capacitor with vacuum (or air) as the dielectric.
