# Capacitance of a plate capacitor increases

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.
