Question

Calculate the number of electrons constituting one coulomb of charge.

Answer 1

One electron possesses a charge of 1.6 × 10^-19C, i.e., 1.6 × 10^-19C of charge is contained in 1 electron.

∴ 1 C of charge is contained in `1/(1.6 xx 10^(-19))`

= 6.25 × 10¹⁸ 

= 6 × 10¹⁸

Therefore, 6 × 10¹⁸ electrons constitute one coulomb of charge.
