The number of electrons in one coulomb of charge is equal to:
Correct answer: A. 6.25×10¹⁸
- A. 6.25×10¹⁸
- B. 1.6×10⁻¹⁹
- C. 6.25x10²¹
- D. 1.6×10⁻²⁷
Explanation
The charge of one electron is approximately 1.6 × 10⁻¹⁹ C. To find the number of electrons in one coulomb, we divide the total charge by the charge of a single electron: n = 1 C / (1.6 × 10⁻¹⁹ C/electron) ≈ 6.25 × 10¹⁸ electrons.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
