Question

Calculate the number of electrons constituting one Coulomb of charge?

Answer 1

The charge of one electron is
`e=1.6 \cdot 10^(-19)C`. In order to have 1 C of charge, we need to have N electrons such that their total charge is 1 C:

`1 C = Ne`
By rearranging the equation, we can easily calculate the number of electrons contained in 1 C of charge:

`N= (1 C)/(e)= (1 C)/(1.6 \cdot 10^(-19)C)=6.25 \cdot 10^(18)`
