Question

One coulomb is equal to charge on 6.25 × 10¹⁸ electrons. What is magnitude of electric charge on a single electron?

Answer 1

If the total charge of 1 coulomb is equal to the combined charge of 6.25 × 10¹⁸ electrons, you can find the charge on a single electron (e) by dividing the total charge by the total number of electrons:

\[e = \frac{1}{6.25 \times 10^{18}} \]

e = 0.16 × 10⁻¹⁸

e = 1.6 × 10⁻¹⁹ C
