Question: a current of 1 ampere is flowing?
Answer: In 1 Ampere of current. 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.
