Farada

Farada refers to a unit of electrical capacitance in the International System of Units (SI). It is named after the English scientist Michael Faraday. One farad is defined as the capacitance of a capacitor across which a potential difference of one volt results in an electric charge of one coulomb. Mathematically, this is expressed as F = C/V, where F is capacitance, C is charge, and V is voltage.

Due to the large magnitude of the farad, it is often expressed in sub-units such as millifarads (mF, 10^-3 F), microfarads (µF, 10^-6 F), nanofarads (nF, 10^-9 F), and picofarads (pF, 10^-12 F) in practical applications. Capacitance is a measure of a system's ability to store electric charge. Capacitors are electronic components designed to exhibit capacitance and are used in a wide variety of electronic circuits for tasks such as filtering, energy storage, and signal coupling. The concept of capacitance is fundamental to understanding electrical circuits and electromagnetism.
