Capacitance - Wikipedia
Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities.
Capacitance | Definition, Formula, Unit, & Facts | Britannica
2024年10月3日 · capacitance, property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. Capacitance also implies an associated storage of electrical energy.

8.2: Capacitors and Capacitance - Physics LibreTexts
Explain the concepts of a capacitor and its capacitance. Describe how to evaluate the capacitance of a system of conductors. A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance.
6.1.2: Capacitance and Capacitors - Engineering LibreTexts
2023年12月21日 · The ability of this device to store charge with regard to the voltage appearing across it is called capacitance. Its symbol is C and it has units of farads (F), in honor of Michael Faraday, a 19th century English scientist who did early work in electromagnetism.
8.7: Capacitance (Summary) - Physics LibreTexts
Capacitors are used to supply energy to a variety of devices, including defibrillators, microelectronics such as calculators, and flash lamps. The energy stored in a capacitor is the work required to charge the capacitor, beginning with no charge on its plates.
2.4: Capacitance - Physics LibreTexts
That is, the capacitance of a system of conductors is uniquely-defined by the physical structure of those conductors, but is unaffected by the amount of charge separated. The units of capacitance are obviously coulombs per volt, which is renamed for brevity to farads.
8.1 Capacitors and Capacitance - University Physics Volume 2
To show how this procedure works, we now calculate the capacitances of parallel-plate, spherical, and cylindrical capacitors. In all cases, we assume vacuum capacitors (empty capacitors) with no dielectric substance in the space between conductors.
8.1 Capacitors and Capacitance – University Physics Volume 2
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as “electrodes,” but more correctly, they are “capacitor plates.”)
10. Capacitances - University of Virginia
The self-capacitance (or just capacitance) is defined as. C = Q/V. It can be understood as a measure of how much charge can be loaded on the conductor before it reaches a given voltage (potential). Experimentally, the relationship is linear for a rigid conductor over a wide range.
