faraday far·a·day (fār'ə-dā')
n.
The electric charge required to deposit or liberate 1 gram equivalent weight of a substance in electrolysis, approximately 9.6494 × 104 coulombs.
faraday
unit of electricity, used in the study of electrochemical reactions and equal to the amount of electric charge that liberates one gram equivalent of any ion from an electrolytic solution. It was named in honour of the 19th-century English scientist Michael Faraday and equals 9.6485309 104 coulombs, or 6.0221367 1023 electrons (see also Avogadro's law).
