Image: Capacitor schematic with dielectric

Description: Schematic of a parallel plate capacitor with a dielectric spacer. Two plates with area

A

{\displaystyle A}

are separated by a distance

d

{\displaystyle d}

. When a charge

±

Q

{\displaystyle \pm {}Q}

is moved between the plates, an electric field

E

{\displaystyle E}

exists in the region between the plates. The dielectric material becomes polarised due to the charge displacement, reducing the total internal field, and increasing the capacitance.
