Colloquially, a capacitor may be called a cap. [2] The utility of a capacitor depends on its capacitance. While some capacitance exists between any two electrical conductors in …

capacitor作为英语名词（n.），中文译为"电容器"，特指能够储存电荷的电子元件。 其发音具有英式 [kəˈpæsɪtə (r)]与美式 [kəˈpæsɪtər]两种变体，常见于电子工程领域的专业语境。

In this article, we'll learn exactly what a capacitor is, what it does and how it's used in electronics. We'll also look at the history of the capacitor and how several people helped shape its progress.

Dec 26, 2025 · A capacitor, also called a condenser, is thus essentially a sandwich of two plates of conducting material separated by an insulating material, or dielectric. Its primary function is …

Feb 15, 2014 · In a circuit, a capacitor acts as a charge storage device. It stores electric charge when voltage is applied across it and releases the charge back into the circuit when needed. A …

Feb 16, 2025 · What is a capacitor? Take two electrical conductors (things that let electricity flow through them) and separate them with an insulator (a material that doesn't let electricity flow …

Aug 6, 2025 · At its core, a capacitor is an electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material …

A capacitor can retain its electric field -- hold its charge -- because the positive and negative charges on each of the plates attract each other but never reach each other.

Jul 10, 2025 · What is a Capacitor? An electronic device containing two terminals that stores and distributes electrical energy is called a capacitor. The main purpose of a capacitor is to store …

Jul 15, 2025 · 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 …
