# How many electrons does it take to make one Ampere?

We know the movement of electrons through a conductor is called a current, and current is measured in amps, but how many electrons does it take to create one amp of current?

An ampere is the current flow of one coulomb per second. One electron carries a charge of -1.6*10^-19 coulombs so one coulomb has 6.25*10^18 electrons. So one ampere is 6.25*10^18 electrons per second.

1 amp is one coulomb per second, and one electron has 1.60217646 × 10-19 coulombs charge, so divide 1 by the charge of the electron to get your huge number of electrons. something like 6x10^18

1 coulomb per second = 1/1.6 x 10^-19 electrons =6.241 509 629 152 65 × 10^18 elementary charges
