What is a Capacitor? Definition, Uses & Formulas | Arrow
Ceramic capacitors contain several plates stacked on top of one another to increase the surface area, while a ceramic material forms the dielectric between the positive and negative poles. Film capacitors wrap these plates against each other, and the dielectric film is usually plastic. Polarized capacitors are electrolytic. An electrolytic ...
Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

How to Make a Capacitor
A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. The strength of this field is called the capacitance of the capacitor. The thinner the insulator and the wider and flatter the conductors, the higher the capacitance.
