Capacitance of a plate capacitor increases

  1. Sep 19, 2004 #1
    How can I show that the capacitance of a plate capacitor increases if a dielectric material fills the space between the plates?

    [tex]C = \varepsilon \frac{A}{d}

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