V.Demonstration:Artificial Dielectric Figure 6.6.2 From the microscopic point of view,the increase in capacitance results because the dipoles adjacent to the electrode induce image charges on the electrode in addition to those from the unpaired charges on the opposite electrode. balanced amplifier 心amp osc. 25555. step-up cage Figure 6.6.3 Demonstration'in which change in capacitance is used to measure the equivalent dielectric constant of an artificial dielectric.
