WebThe dielectric constant, k, is a property of the specific dielectric being used; it indicates how much the capacitance increases when a given dielectric is used. The higher the dielectric constant, the better a material functions as an insulator---for example, rubber has a very high dielectric constant, and so it is often used a protective ...
