No headers Let us imagine (Figure (V.)10) that we have a capacitor of capacitance (C) which, at some time, has a charge of (+q) on one plate and a charge of (-q) on the other plate. The potential difference across the plates is then (q/C). Let us now take a ...

Physics A level revision resource: Introduction to capacitors

A battery stores electrical energy and releases it through chemical reactions, this means that it can be quickly charged but the discharge is slow. Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference.

OverviewNon-ideal behaviorHistoryTheory of operationCapacitor typesCapacitor markingsApplicationsHazards and safety

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
