Show that one ampere is equivalent to a flow of [tex]6.25 \times 10^{18}[/tex] elementary charges per second.
Answer (2)
It's not. It's equivalent to the transfer of that many elementary charges every second .
The elementary charge (charge on an electron) is
1.60 x 10⁻¹⁹ coulomb / electron.
The number of electrons in a Coulomb is the reciprocal of that number.
6.25 x 10⁻¹⁸ electrons / Coulomb.
There's the number. 1 Coulomb per second is called 1 Ampere.
One ampere is defined as the flow of one coulomb of charge per second, which is equivalent to approximately 6.25 × 1 0 18 elementary charges per second. This calculation is based on the charge of a single electron, which is about 1.602 × 1 0 − 19 coulombs. Thus, in one coulomb, there are approximately 6.25 × 1 0 18 electrons flowing per second when a current of one ampere is present.
