==Key Stage 5==
===Meaning===
[[Capacitance]] is the ability of a [[system]] to store an [[Electrical Charge|electric charge]] per [[unit]] of [[Potential Difference|potential difference]] (pd), [[measure]]d in [[farad]]s (F).

===About Capacitance===

*The [[unit]] of [[capacitance]] is the [[farad]] (F), which is equal to one [[coulomb]] per [[volt]].
*Factors affecting capacitance include the area of the plates, the distance between them, and the [[dielectric]] [[material]] between the plates.
*[[Capacitor]]s in [[Series Circuit|series]] have a reduced total [[capacitance]], while those in [[Parallel Circuit|parallel]] have an increased total [[capacitance]].
*[[Capacitance]] is a [[measure]] of a [[capacitor]]'s ability to store [[Electrical Charge|charge]].
*In [[Direct Current|DC]] [[Electrical Circtuit|circuits]], a [[capacitor]] charges and discharges, storing and releasing [[Energy|energy]].
*In [[Alternating Current|AC]] [[Electrical Circuit|circuits]], [[capacitor]]s block direct [[Electrical Current|current]] and allow [[Alternating Current|alternating current]] to pass, acting as a reactive component.

===Formula===
The [[capacitance]] 𝐶 of a [[capacitor]] is given by:

𝐶=𝑄𝑉

Where:

𝐶 is the [[capacitance]] of the [[capacitor]]

𝑄 is the [[Electrical Charge|charge]] stored in the [[capacitor]]

and

𝑉 is the [[Potential Difference|potential difference]] across the [[capacitor]].

===Examples===

*A [[parallel-plate capacitor]] consists of two conductive plates separated by an insulating material.
*Used in electronic circuits to store energy, filter signals, and in timing applications.
