a fundamental physical constant equal to the product of Avogadro’s number NA and the charge of the electron e. The Faraday constant equals (9.648456 ± 0.000027) × 104 coulombs per mole. It is widely used in electrochemical calculations. The constant is named after M. Faraday, who discovered the fundamental laws of electrolysis.
