Importance of dielectric constant
Commercially manufactured capacitors typically use a solid dielectric material with high permittivity as the intervening medium between the stored positive and negative charges. This material is often referred to in technical contexts as the capacitor dielectric. The most obvious advantage to using such a dielectric material is that it preve… WitrynaSignificance of Dielectric Constant. The significance of dielectrics is the ability to assist in voltage potential by holding off electrical fields from circuit components. The …
