Calculate the number of electrons that is present in 1coulomb of charge |
|
Answer» 1.6×10^-19 1.6×10^-19 We know that the charge on an electron is negative and it is -1.6⨯10-19\xa0coulomb.We need to calculate\xa0the number of electrons constituting one coulomb of charge.e = 1.6 × 10-19\xa0CTotal charge required for 1Coulomb.∴ q = 1C……….(1)The formula to calculate the charge isq = newhereq = chargee = number of electronsn = q/e……….(2)Substituting equation (1) in equation (2) we getn = 1/(1.6 × 10-19)n = 6.25\xa0× 1018\xa0electrons\xa0≅ 6\xa0× 1018\xa0electronsSo 1 Columb of charge contains\xa06\xa0× 1018\xa0electrons 1.6×10*-19 1.6 × 10^-19 |
