1 Coulomb = ___________ e.
- A. 6×10-19
- B. 6.25×1018
- C. 1.6×1019
- D. 6.25×10-18
Explanation
One coulomb equals the charge of approximately 6.25 × 10^18 electrons, since the charge of one electron is about 1.6 × 10^-19 coulomb. The negative sign belongs to each electron’s charge, not to the number of electrons.
