Calculate the no of electron constituting 1coulomb charge

1.	Calculate the no of electron constituting 1coulomb charge
Answer» We know that the charge on an electron is negative and it is -1.6⨯10-19 coulomb.We need to calculate\xa0the number of electrons constituting one coulomb of charge.e =1.6 × 10-19 CTotal charge required 1Coulomb.Therefore q = 1CWe know the formulaq=nen =q/e—–(i)Hence, 1 C charge is carried bySubstituting the values in equation (i) we get,1/ (-1.6⨯10-19) = 6.25 ⨯ 1018 electrons.So, if 1 A current flows through a conductor, then6.25 ⨯ 1018 electrons pass per a second across the cross-section of the conductor.
