Calculate the number of electrons constituting one coulomb of charge.

Charge on one electron (e) = 1.6 × 10 -19 C q = 1 C Let n electrons constitute one coulomb of charge. ∴ q = ne where, q = charge e = charge on one electron n = number of electrons ⇒ n = ⇒ n = = 6.25 x 10 -18 ≈ 6 x 10 -18 Therefore, the number of electrons constituting one coulomb of charge is 6 x 10 -18
