How can I show that the capacitance of a plate capacitor increases if a dielectric material fills the space between the plates?

C = \varepsilon \frac{A}{d}


The permittivity is what you're interested in. A dielectric material has a higher permittivity than \varepsilon_0, the permittivity of free space.
