Dielectric constant of cardboard
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 ... WebNov 8, 2024 · This analysis can be performed "in reverse" to determine the force exerted on a partially-inserted dielectric by the capacitor. In Physics 9A, we learned that the force due to a potential energy field is equal to the negative of the gradient of the potential energy (see Physics 9A Libretext, Section 3.6 ): (2.5.4) F → = − ∇ → U.
