Electric capacitance is a property of a conductor or a system of conductors that characterizes its ability to store an electric charge. It is defined as the ratio of the magnitude of the charge on one of the conductors to the electric potential difference between the conductors. The SI unit of electric capacitance is the farad (F), named after Michael Faraday.
Capacitors, which are devices designed to store electric charge, are the most common example of capacitance in action. They are widely used in electronic circuits to store and discharge electric charge as needed. Capacitance is also an important concept in the study of electromagnetic waves and fields.
The ability to store charge is also useful in many other areas of technology, such as in batteries, where capacitance plays a role in the ability of the battery to hold and deliver electrical energy. Capacitance is also used in various sensing and measuring applications, such as in touch screens and pressure sensors.
