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. In other words, …
Structure and Degradation of Aluminum Electrolytic Capacitors
Aluminum Electrolytic Capacitors (AECs) are used at the dc-link of power electronic converters (PECs) as an energy buffer. During their lifecycle operation, various voltage and current stresses are imposed on these capacitors. These stresses lead to the degradation and hence, the failure of the AEC. This paper is based on studying the internal structure …

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
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 …
A capacitor is a passive two-terminal electrical device, which stores electrical energy in form of an electric field. It was invented by Ewald Georg von Kleist. A capacitor is otherwise …
The main purpose of having a capacitor in a circuit is to store electric charge. For intro physics you can almost think of them as a battery. . Edited by ROHAN NANDAKUMAR (SPRING 2021).

Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
The English scientist Henry Cavendish (1731–1810) determined the factors affecting capacitance. The capacitance (C) of a parallel plate capacitor is…directly proportional to the area (A) of one plate; inversely proportional to the separation (d) between the plates; directly proportional to the dielectric constant (κ, the Greek letter kappa) of the material between …
The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron. It …
The city of Athens lived under a radically democratic government from 508 until 322 BCE. Before the earlier date there was democracy to be found here and there in the government of Athens, and democratic institutions survived long after the latter date, but for those 186 years the city of Athens was self-consciously and decidedly democratic, …

Summary. A capacitor is…. a device for storing separated electric charges. a pair of oppositely charged conductors (called plates even if they aren''t flat) separated by an insulator (called a dielectric).; The capacitance (C) of an electrostatic system is, by definition, the ratio of the quantity of charge separated (Q) to the potential difference applied (V).
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
