The farad (symbol F) 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 equivalent expressions in other SI units are: Since the farad is a very large unit, values of capacitors are usually expressed in microfarads (?F), nanofarads (nF), or picofarads (pF). The picofarad is comically called a "puff" in laboratory usage.
