What is capacitance? - Fluke Corporation
网页Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge. Capacitors are energy-storing devices available in many sizes and shapes.
Capacitor and Capacitance - Formula, Uses, Factors Affecting ...
网页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.
8.1 Capacitors and Capacitance - University Physics Volume 2
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:

网页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 …
2.4: Capacitance - Physics LibreTexts
网页Definition of Capacitance. Imagine for a moment that we have two neutrally-charged but otherwise arbitrary conductors, separated in space. From one of these conductors we remove a handful of charge (say \(-Q\)), and place it on the other conductor. Figure 2.4.1 – Charge Separated to Two Conductors
