current = q/t.
1 A =n× 1.6×10^-19 C/ 1 sec.,where n is the no. of electrons.
n = 1/1.6×10^-19
n = 1.6×10^19 electrons.
1 A =n× 1.6×10^-19 C/ 1 sec.,where n is the no. of electrons.
n = 1/1.6×10^-19
n = 1.6×10^19 electrons.

Given that
Charge (Q) = 1 C
Electron (e) = 1.6× 10^-19
Number of electron (n) = ?
Q= ne
1 C = n × 1.6×10^-19 C
n = 1/(1.6×10^-19)
n = 6.25 × 10^18 electron
