Understanding Farads and Capacitance Units

A farad (symbol: F) is the unit of electrical capacitance. It is defined as the charge in coulombs that a capacitor can store per volt of potential difference between its plates. The farad is named after Michael Faraday, an English scientist who did significant work on electricity and magnetism.

One farad is a large unit of capacitance, so smaller units such as the microfarad (μF) and nanofarad (nF) are often used to measure smaller capacitances. For example, a typical ceramic capacitor might have a capacitance of 100 nF or 0.1 μF.
