Question.
Calculate the number of electrons constituting one coulomb of charge.
Calculate the number of electrons constituting one coulomb of charge.
solution:
Number of electrons constituting 1 coulomb is given by,
$\mathrm{n}=\frac{\mathrm{Q}}{\mathrm{e}}$ Where, $\mathrm{Q}=1 \mathrm{C}$ and $\mathrm{e}=$ charge of a single electron $=1.6 \times 10^{-19} \mathrm{C}$
or $\mathrm{n}=\frac{1 \mathrm{C}}{1.610^{-19} \mathrm{C}}=6.24 \times 10^{18}$ electrons.
