Coulomb (SI Unit of Electric Charge)

Introduction : The coulomb is the standard SI unit for electric charge, representing the charge transported by a constant current of one ampere in one second. It's fundamental in electromagnetism, electronics, and electrical engineering.

History & Origin : Named after French physicist Charles-Augustin de Coulomb (1736–1806), who formulated Coulomb's Law. Adopted as the SI unit in 1946, replacing earlier electrostatic and electromagnetic units.

Current Use : Used to quantify battery capacity, capacitor ratings, and electrostatic charges. Essential in circuit design, electrochemistry, and particle physics (e.g., electron charge = ~1.602×10⁻¹⁹ C).

Ampere-Hour (Battery Capacity Unit)

Introduction : The ampere-hour measures charge capacity in batteries, representing 1 ampere of current flowing for 1 hour (3,600 coulombs). It's the standard unit for consumer electronics and automotive batteries.

History & Origin : Emerging with early 20th-century battery technology, it became entrenched as a practical measure for energy storage, especially in lead-acid and lithium-ion systems.

Current Use : Used to rate smartphone batteries (e.g., 3,000 mAh), electric vehicle packs (e.g., 100 kWh ≈ 270 A·h at 370V), and backup power systems.
