Calculate the number of electrons constituting one coulomb of charge.
One electron possesses a charge of 1.6 ×10-19 C, i.e., 1.6 ×10-19 C of charge is contained in 1 electron.
∴ 1 C of charge is contained in 1 / 1.6 x 10-19
= 6.25 x 1018 = 6 x 1018
Therefore, 6 x 1018 electrons constitute one coulomb of charge.
