Question

Calculate the number of electrons that flow per second to constitute a current of one amphere. Charge on an electron is 1.6×10 raised to -19 C.

Answer 1

$0.625 \times {10}^{19} c$

$q = ne$

I=q/t

1A=1c/1s

1c=0.625×10^19

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
