n. [ From Michael Faraday, the English electrician. ] (Elec.) the quantity of electric charge that, passed though an ionic solution, will cause electrolysis of one equivalent of ions; it is equal to about 96, 490 coulombs. The number of univalent metal ions (such as silver in a silver nitrate solution) which would be deposited as free metal by such a current is Avogadro's number, 6.023 x 1023. [ PJC ]
