Faraday

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 The faraday is no longer in general use and has been replaced by the SI unit coulomb; one faraday is approximately equivalent to 96485.3415 coulombs.

Like the farad, the faraday was named after Michael Faraday.

• Faraday cage

A Faraday cage is a closed metal chamber, sometimes made of wire mesh in which the electric field is zero. Because ideal metals contain free electrons, an external electric field applied to a metal surface generates a current which in turn generates a counter cancelling electric field. An electric field can not penetrate a metal surface and therefore the electric field inside a Faraday cage is always zero.
