one second of current that quietly contains 6.24 quintillion electrons doing your bidding
means The SI unit of electric charge, equal to the amount of charge carried by a steady current of one ampere in one second.
from Named for the French physicist Charles-Augustin de Coulomb, who in the late 18th century measured the forces between electric charges with a delicate twisting balance — giving us Coulomb's law. His surname became the unit, joining the small pantheon of scientists turned into lowercase measurements (the volt, the watt, the ohm), where 'coulomb' now quietly counts the charge while the man's name carries the current.
