Question

calculate the number of electrons constituting one coulomb of charge

Answer 1

we know that the charge of 1 electron = 1.6 x 10power minus19 coulomb
thus, 1.6 x 10power minus 19C of charge=1 electron.
therefore 1C= 1/1.6 x 10 power minus 19 electrons
                    = 10 power19/1.6 electrons
                    = 10 x 10power 18/1.6 electrons
                    =6.25 x 10 power18 electrons

Answer 2

HELLO THERE!

By Milikan's Oil Drop experiment, it has been found that the charge of 1 electron is  -1.6 x 10⁻¹⁹ Coulomb (C).

Now, -1.6 x 10⁻¹⁹C charge is possessed by 1 electron.

Hence, 1 C charge is possessed by:

electrons.
