How do capacitors work?

Capacitors use dielectrics made from all sorts of materials. In transistor radios, the tuning is carried out by a large variable capacitor that has nothing but air between its plates. In most electronic circuits, the capacitors are sealed components with dielectrics made of ceramics such as mica and glass, paper soaked in oil, or plastics such ...

Exploring Capacitive Materials: Properties and Applications | Langir

What Are Capacitors. Capacitors, also known as condensers, are electronic components that utilize capacitive materials to store and release electrical energy. They consist of two conductive plates separated by a dielectric material. When a voltage is applied across the plates, an electric field is formed, leading to the storage of electric charge.
