Dielectrics

Charge polarization of a dielectric placed between the plates of a capacitor causes a surface charge on the two surfaces of the dielectric.

This allows a greater charge Q to be on the capacitor for a given voltage. This increases the capacitance of the capacitor.

The dielectric constant is kappa, .
