Principles for selecting the capacity of capacitors
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

Types of Capacitors: Definition, Diagram, Working, Uses [PDF]
The types of capacitors are categorized as follows based on polarization: Polarized; Unpolarized; A polarized capacitor, also known as an electrolytic capacitor, is a crucial component in an electronic circuit. These capacitors are used to achieve high capacitive density. Unpolarized capacitors are preferred over fully charged capacitors.
Resistors Capacitors and Inductors
Capacitors store electrical energy, somewhat like rechargeable batteries. Unlike batteries, they tend to have a lower capacity to store charge and also discharge very quickly. In a capacitor, energy is stored by polarizing a dielectric (insulating) material. As energy is added to the capacitor, more charge separation occurs in the dielectric ...
