Question

Calculate the number of electrons passing per second through a conductor to produce a
current of one ampere.
(Charge on electron =16x10-19 coulomb)

Answer 1

we know
I=q/t
1=q/1
then,q=1
q=ne
1=n×16×10^-19
n=1/16×10^-19
n=6.25×10^18

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
