What does your textbook say about 2.13 EFFECT OF DIELECTRIC ON CAPACITANCE?
With the understanding of the behavior of dielectrics in an external field developed in Section . , let us see how the capacitance of a parallel plate capacitor is modified when a dielectric is present. As before, we have two large plates, each of area A, separated by a distance d. The charge on the plates is ±Q, corresponding to the charge density ±σ (with σ = Q/A). When there is vacuum between the plates,
