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).
Milliampere-hour (mAh)
Definition: A milliampere-hour (symbol: mAh) equals one thousandth of an ampere-hour (10⁻³ Ah). Common for smaller batteries.
History: Became standard with the miniaturization of electronic devices in the late 20th century.
Current use: Universal unit for small rechargeable batteries (e.g., wireless earbuds ~50mAh, smartwatches ~300mAh).
