GENERAL KNOWLEDGE

Detailed explanation-1: -Capacitors are simply devices that consist of two conductors carrying equal but opposite charges. A simple parallel-plate capacitor consists of two equally-sized metal plates, known as electrodes, separated by an insulator, known as a dielectric, held parallel to each other.

Detailed explanation-2: -The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates.

Detailed explanation-3: -There are many applications which use capacitors as energy sources. They are used in audio equipment, uninterruptible power supplies, camera flashes, pulsed loads such as magnetic coils and lasers and so on.

Detailed explanation-4: -Capacitors are electrical devices for electrostatic energy storage. There are several types of capacitors developed and available commercially. Conventional dielectric and electrolytic capacitors store charge on parallel conductive plates with a relatively low surface area, and therefore, deliver limited capacitance.

Detailed explanation-5: -Dielectric Material – the type of material which separates the two plates called the “dielectric”, the higher the permittivity of the dielectric the greater the capacitance.
