A unit of electric charge equal to the amount moved by a current of one ampere in one second

has the identical value but is expressed as the product of current and time

Surface Forms

ampere-second singular

Morphology

ampere-second = ampere + second (transparent) = ampere + second

A direct hyphenated compounding of two unit names indicating the product of current and time (charge), so learners knowing both units can infer the meaning.

Etymology

Ampere-second combines ampere, named for the French scientist André-Marie Ampère, and second, the basic unit of time. It means the amount of electric charge moved by a flow of one ampere in one second, so one ampere-second equals one 'coulomb'.
