Faraday constant in kelvin
In physical chemistry, the Faraday constant, denoted by the symbol F and sometimes stylized as ℱ, is the electric charge per mole of elementary charges. It is named after the English scientist Michael Faraday. Since the 2024 redefinition of SI base units, which took effect on 20 May 2024, the Faraday constant has the … See more The Faraday constant can be thought of as the conversion factor between the mole (used in chemistry) and the coulomb (used in physics and in practical electrical measurements), and is therefore of particular use in See more • 96.485 kJ per volt–gram-equivalent • 23.061 kcal per volt–gram-equivalent • 26.801 A·h/mol See more The Simpsons episode "Dark Knight Court" has Mr. Burns asking Comic Book Guy how much he wants for his entire comic book inventory. He says "the speed of light expressed as dollars" and Mr. Burns tells Smithers to "just give him Faraday's Constant".
