Current (i) is given by the formula
i = nQ/t
Where
n : Number of charged particles
Q : Charge of the particle (1.6 × 10⁻¹⁹ C for electron)
t : Time
n = it / Q
= 4 A × 1 s / (1.6 × 10⁻¹⁹ C)
= 2.5 × 10¹⁹
∴ 2.5 × 10¹⁹ electrons pass in 1 second.

→ Formula of Current,
i = nQ/t
--------------------
→ n = it / Q
= 4 A × 1 s / (1.6 × 10⁻¹⁹ C)
= 2.5 × 10¹⁹
-------------------
∴ 2.5 × 10¹⁹ electrons pass in 1 second.
