of one mole of elementary charges (approximately , the Avogadro number) is known as a faraday unit of charge (closely related to the Faraday constant). One faraday equals In terms of the Avogadro constant (NA), one coulomb is equal to approximately × NA elementary charges. A capacitor of one farad can hold one coulomb at a drop of one volt. One ampere hour equals 3600 C, hence = 3.6 C. One statcoulomb (statC), the obsolete CGS electrostatic unit of charge (esu), is approximately 3.3356 C or about one-third of a nanocoulomb. In everyday terms The charges in static electricity from rubbing materials together are typically a few microcoulombs. The amount of charge that travels through a lightning bolt is typically around 15 C, although for large bolts this can be up to 350 C. The amount of charge that travels through a typical alkaline AA battery from being fully charged to discharged is about 5 kC = 5000 C ≈ 1400 mA⋅h. A typical smartphone battery can hold 10,800 C ≈ 3000 mA⋅h.
