18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

This way, we can use k as the relative permittivity of our dielectric material times the permittivity of space, which is 8.854E-12 F/m. Note that k = 1 for air.. So the area of the plates and the distance between them are things that we can change based on how we construct our capacitor.
Explaining Capacitors and the Different Types | DigiKey
One common distinction to note is that between electrolytic and non-electrolytic capacitor types. Electrolytic capacitors use a dielectric material which is formed in-place electrochemically, usually by oxidizing the surface of the electrode material, whereas non-electrolytic (often called "electrostatic" capacitors) use dielectric ...
