Question

Calculate the number of electron in coulomb of charge

Answer 1

Calculate the number of electron constituting 1 coulomb of charge. 6.25 ⨯ 10 ^18 electrons pass per a second across the cross section of the conductor.

Answer 2

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
