CAPACITORS, CAPACITANCE, AND DIELECTRICS

Embedding the capacitor in an ideal dielectric (or less ideally multiple dielectrics) does not change the result. Ideally, the effect of the dielectric is proportional to the (free) charge So usually the capacitor should end up nearly overall neutral by itself with charges of equal magnitude and opposite sign on the plates.

Why Do We Use Dielectric Material In Capacitor?

Dielectrics are used in capacitors in order to increase the capacitance. This is because dielectrics increase the ability of the medium between the plates to resist ionization, which in turn increases the capacitance.
