For other uses, see Faraday (disambiguation).
In physics, the faraday (not to be confused with the farad) is a unit of electrical charge; one faraday is equal to the charge of 6.02 × 1023 electrons (one mole). The faraday is no longer in general use and has been replaced by the SI unit coulomb; one faraday is approximately equivalent to 96485.3415 coulombs.
The value of a faraday, F, can easily be calculated:
where
- Na is Avogadro's number (6.022 ×1023 mol-1)
- e is the elementary charge (1.602 ×10-19 C)
Like the farad, the faraday was named after Michael Faraday.
