The Faraday constant F is the charge carried by one mole of electrons. F = L e, where L is the Avogadro constant and e is the elementary charge.
Use coulombs consistently and remember that one electron carries charge e, while one mole carries F. This relationship connects microscopic charge to measurable electrolysis.
Using L≈6.02×10²³ mol⁻¹ and e≈1.60×10⁻¹⁹ C gives F≈9.65×10⁴ C mol⁻¹.
F is not the charge on one electron, and the symbol L here is not a current or length variable.
