6 FAQs about [Capacitor Two Dielectric Formulas]
How many dielectrics are in a capacitor?
Let us first suppose that two media are in series (Figure V. V. 16). Our capacitor has two dielectrics in series, the first one of thickness d1 d 1 and permittivity ϵ1 ϵ 1 and the second one of thickness d2 d 2 and permittivity ϵ2 ϵ 2. As always, the thicknesses of the dielectrics are supposed to be small so that the fields within them are uniform.
Does a dielectric affect a capacitor's capacitance?
As we discussed earlier, an insulating material placed between the plates of a capacitor is called a dielectric. Inserting a dielectric between the plates of a capacitor affects its capacitance. To see why, let’s consider an experiment described in Figure 8.5.1 8.5. 1.
How do you find the total capacitance of a dielectric?
As always, the thicknesses of the dielectrics are supposed to be small so that the fields within them are uniform. This is effectively two capacitors in series, of capacitances ϵ1A/d1 and ϵ2A/d2 ϵ 1 A / d 1 and ϵ 2 A / d 2. The total capacitance is therefore C = ϵ1ϵ2A ϵ2d1 +ϵ1d2.

Does insertion of a dielectric affect a battery's capacitance?
Once the battery becomes disconnected, there is no path for a charge to flow to the battery from the capacitor plates. Hence, the insertion of the dielectric has no effect on the charge on the plate, which remains at a value of Q0 Q 0. Therefore, we find that the capacitance of the capacitor with a dielectric is
