Capacitance - Wikipedia
网页The most common units of capacitance are the microfarad (μF), nanofarad (nF), picofarad (pF), and, in microcircuits, femtofarad (fF). Some applications also use supercapacitors that can be much larger, as much as hundreds of farads, and parasitic capacitive elements can be less than a femtofarad.

网页2024年8月5日 · The capacitance C is the ratio of the amount of charge q on either conductor to the potential difference V between the conductors, or simply C = q/V. In both the practical and the metre–kilogram–second scientific systems, the unit of electric charge is the coulomb and the unit of potential difference is the volt , so that the unit of ...
Farad - Wikipedia
网页The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI), equivalent to 1 coulomb per volt (C/V). [1] It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg −1 ⋅m −2 ⋅s 4 ⋅A 2.
8.2: Capacitors and Capacitance - Physics LibreTexts
网页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, capacitance is the largest amount of charge per volt that can be stored on the device: \[C = \frac{Q}{V} \label{eq1}\]
8.7: Capacitance (Summary) - Physics LibreTexts
网页The capacitance of a capacitor is a parameter that tells us how much charge can be stored in the capacitor per unit potential difference between its plates. Capacitance of a system of conductors depends only on the geometry of their arrangement and physical properties of the insulating material that fills the space between the conductors.

2.4: Capacitance - Physics LibreTexts
网页The units of capacitance are obviously coulombs per volt, which is renamed for brevity to farads. A coulomb is a rather large amount of charge, and for most real-world applications of capacitance, we will see significantly less than a farad of capacitance, typically in the range of microfarads (μF).
Capacitors - Summary – The Physics Hypertextbook
网页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). The SI unit of capacitance is the farad [F], which is equivalent to the coulomb per volt [C/V]. One farad is generally considered a large capacitance.
