Plastic dielectric
Capacitor
A capacitor, in its simplest form, is two conductive plates separated by a dielectric.

the charge on the capacitor had increased.
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
the same as any capacitor tantalum has a very high dielectric constant so these are smaller physically the electrolite is solid so the capacitance is very stable
When a dielectric material becomes a conductor, it loses its insulating properties, allowing electric current to flow through it. This results in the loss of the dielectric function, as the material no longer acts as an electrical insulator. The material will exhibit conductive behavior and may be subject to resistive heating effects.

Electrolytic capacitors use aluminium as a dielectric.
The element of a capacitor is a dielectric material, which is the insulating layer between the two conductive plates. This dielectric material helps store electrical energy by preventing the plates from touching and forming a short circuit.
Changing the dielectric causes the capacitance to change.
