Question

The SI unit of electric charge 'coulomb' is eqivalent to the charge contained in the 6.25 ? 10^18 electrons. Briefly explain the statement.

Answer 1

Dear Student

Electric charge is a fundamental property of matter. Electrons carry a charge of negative one "electron unit", and protons a charge of positive one "electron unit".
The unit electric charge is the amount of charge contained in a single electron
The SI unit for electric charge is the Coulomb.
So relation between these two units of charge is
1C = n x charge on electron (e)
q = ne
n =q/e =1/1.6 x 10^-19
n = 6.25 x 10²⁸

So 1 Colulomb = charge on 6.25 x 10²⁸ electrons
