定義
SIの電荷の単位で、1アンペアの電流が1秒間に運ぶ電荷量として定義される（1 C = 1 A·s）。約6.242×10¹⁸個の電気素量に相当。
解説
Named after Charles-Augustin de Coulomb. A standard AA battery holds roughly 9,000–10,000 coulombs of charge. The elementary charge of one electron is 1.602×10⁻¹⁹ coulombs — meaning one coulomb represents about 6.24 billion billion electrons. Phone battery capacity is measured in milliamp-hours (mAh); a 3,000 mAh battery stores 3 A × 3,600 s = 10,800 C.
