Question

How many electrons carry one coulomb of charge?

Options

• 6.02 × 10²¹

• 6.24 × 10¹⁸

• 6.24 × 10¹⁵

• 6.02 × 10¹⁶

Answer 1

6.24 × 10¹⁸

Explanation:

The charge on one electron is 1.602 × 10⁻¹⁶ C. So, the number of electrons in 1 coulomb is `1/(1.602 xx 10^-19)` ≈ 6.24 × 10¹⁸

Thus, 6.24 × 10¹⁸ electrons carry one coulomb of charge.
