Ampere-hour (Ah)

Definition: An ampere-hour (symbol: Ah) equals the charge transferred by one ampere flowing for one hour (1Ah = 3600C). A practical unit for battery capacity.

History: Developed in the early 20th century as battery technology advanced, providing a convenient measure for energy storage.

Current use: Standard unit for rating battery capacity in automotive, solar, and consumer electronics (e.g., smartphone batteries range 2-5Ah).

Coulomb (C)

Definition: The coulomb (symbol: C) is the SI derived unit of electric charge, defined as the charge transported by a constant current of one ampere in one second (1C = 1A × 1s).

History: Named after Charles-Augustin de Coulomb. Adopted as part of the metric system in 1881, its definition is now tied to the ampere and second.

Current use: Fundamental to electrochemistry (Faraday's law), capacitor ratings, and particle physics (elementary charge is ~1.602×10⁻¹⁹ C).
