1 microampere contains number of electrons. The charge on one electron is coulombs. This can be used to deduce the number of electrons that 1 microampere contains. Since, 1 coulomb = electrons And we know that, “1 ampere” is equal to “1 coulomb per second”, 1 ampere = electrons/sec

The ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 ×1018 electron or one Coloumb per second constituting one ampere

1 coulomb = 1/1.602 × 10^-19 = 6.24 × 10^18 electrons. An electric current of 1 ampere is equal to 1 coulomb of charge passing a point in a circuit every second: Therefore a current of 1 ampere = 6.242 × 10^18 electrons moving past any point in a circuit every second.
