How does a dielectric work?
The free charges on the capacitor plates generate an applied electric field E 0. When a dielectric is placed between the plates, this field exerts a torque on the electric dipoles within the dielectric material. These dipoles align with the field, creating induced bound charges on the dielectric surfaces.
