- The elementary charge of an electron (e) is approximately 1.602 × 10-19 coulombs.
- Current (I) is defined as the flow of electric charge (Q) per unit time (t): I = Q / t.
- 1 ampere (A) of current represents the flow of 1 coulomb (C) of charge per second.
To find the number of electrons flowing per second in 1 ampere of current, we use the formula:
- Number of electrons (n) = Total charge (Q) / Charge of one electron (e)
- n = 1 C / 1.602 × 10-19 C/electron
- n ≈ 6.242 × 1018 electrons
This calculation shows that 1 ampere of current is equal to the flow of approximately 6.242 × 1018 electrons per second.
