Farad

The farad is the SI unit of capacitance (named after Michael Faraday). A capacitor has a value of one farad when one coulomb of charge causes a potential difference of one volt across it. Its dimensions in SI units are:

Since the farad is a very large unit, values of capacitors are usually expressed in microfarads (μF), nanofarads (nF), or picofarads (pF). The farad should not be confused with the faraday, an older unit of charge nowadays deprecated in favour of the coulomb.
