Capacitance - Wikipedia
Capacitance is the ability of an object to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities.
Capacitance | Definition, Formula, Unit, & Facts | Britannica
2025年1月8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.
What is capacitance? - Fluke Corporation
Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791–1867).

2024年11月17日 · 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:
Capacitance: Definition, Factors Affecting, Formula, Unit & FAQs
2024年2月4日 · The substance that stores the electric charge is called a capacitor, i.e. the ability of the capacitor to hold the electric charge is called capacitance. It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the voltage applied.
Capacitor and Capacitance - Formula, Uses, Factors Affecting ...
Capacitance is the ratio of the change in the electric charge of a system to the corresponding change in its electric potential. The capacitance of any capacitor can be either fixed or variable, depending on its usage.
8: Capacitance - Physics LibreTexts
Capacitors are important components of electrical circuits in many electronic devices, including pacemakers, cell phones, and computers. In this chapter, we study their properties, and, over the next few chapters, we examine their function in combination with other circuit elements.
Capacitance Definition & Meaning - Merriam-Webster
The meaning of CAPACITANCE is the property of an electric nonconductor that permits the storage of energy as a result of the separation of charge that occurs when opposite surfaces of the nonconductor are maintained at a difference of potential.
Capacitance | Definition, Calculation & Analogy - Magnetism
Capacitance is defined as the ability to store an electric charge and is symbolized by the capital letter C. Any two conductors separated by an insulator (or a vacuum) form a capacitor. Commonly recognized are two closely related notions of capacitance: self-capacitance and …
What is Capacitance - Definition, Formula, and Example - Matmake
Capacitance is a measure of an object’s ability to store electrical charge when a potential difference (voltage) is applied across it. It is defined as the ratio between the amount of energy stored in an object and the amount of charge applied to it.
