Is AMPS the number of coulombs per second or 1.6x10^-19 per seconds?

1 Answer

Answer :

not sure, but according to wikipedia: http://en.wikipedia.org/wiki/Ampere “a current of one ampere is one coulomb of charge going past a given point per second” or more specifically “Since a coulomb is approximately equal to 6.24150948×1018 elementary charges, one ampere is approximately equivalent to 6.24150948×1018 elementary charges, such as electrons, moving past a boundary in one second.”
