Question

Calculate the No. of electron constituting 0.1 coulomb of charge.​

Answer 1

Answer:

Charge of one electron=1.6 x 10⁻¹⁹ C

If charge is 1 coulomb then number of electrons= 1/1.6 x10⁻¹⁹

=10¹⁹/1.6

=6.25 x 10¹⁸

Answer 2

We know that charge of electron e=1.6 x 10-19C

No. of electrons n can be given by n=Q/e

n= 0.1c/1.6 x 10-19

n=6.25 x 1017 electrons.
