We know that the charge on an electron is negative and it is -1.6⨯10-19 coulomb.
We need to calculate the number of electrons constituting one coulomb of charge.
e = 1.6 × 10-19 C
Total charge required for 1Coulomb.
∴ q = 1C……….(1)
The formula to calculate the charge is
q = ne
where
q = charge
e = number of electrons
n = q/e……….(2)
Substituting equation (1) in equation (2) we get
n = 1/(1.6 × 10-19)
n = 6.25 × 1018 electrons ≅ 6 × 1018 electrons
So 1 Columb of charge contains 6 × 1018 electrons.
