Answer 2

|| ✰✰ ANSWER ✰✰ ||

➼➼6.25 ⨯ 10^18 electrons.

||✪✪ Explanation ✪✪||

We know that the charge on an electron is negative and it is -1.6⨯10-19 coulomb.

We need to calculate the number of electrons constituting one coulomb of charge.

e =1.6 × 10^-19 C

Total charge required 1Coulomb.

Therefore q = 1C

We know the formula

q = ne

n = q/e—–(i)

Hence, 1 C charge is carried by

Substituting the values in equation (i) we get,

1/ (-1.6⨯10^-19)

= 6.25 ⨯ 10^18 electrons.

So, if 1 A current flows through a conductor, then  6.25 ⨯ 10^18 electrons pass per a second across the cross-section of the conductor.
