The number of electorns delivered at the cathode during electrolysis by a current of 1 ampere in 60 seconds is (charge on electron = 1.60 × 10–19 C)

Total number of coulombs passed = i x t = 1 x 60 = 60No. of Electrons transformed=Total coulombs passedCharge on electron in Coulomb                                               =601.6×10-19 =3.75×10-20
