Guide to Ceramic Capacitor Dielectrics and Other Types
The strength of the electric field in the capacitor dielectric determines how displacement current arises through the device, thus we can categorize capacitors based on their insulating dielectric. In this article, we discuss the categorization of capacitor dielectrics, including a section dedicated to ceramic capacitor dielectrics.

8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. ...
