Question

What electrical unit no of electerons moving through a circuit per second

Answer 1

One ampere is equivalent to one Coulomb of charge flowing per second. Since each electron carries 1.6 x 10-19 Coulombs of charge, a current of one ampere represents a flow of (1/1.6) x 10+19 electrons or 6.22 x 10+18 electrons each second.
