Question

calculate the number of electrons constituting one coulomb of charge

Answer 1

We know that the a electron have charge of 1.6 × 10−19 C
∴ e =1.6 × 10−19 C
Total charge required 1Coulomb.
∴ q = 1C
Since q=ne
⇒ n =q/e
⇒ n = 1/1.6 × 10−19
⇒6.25×10^1 8
⇒6×10^1 8electrons.

Answer 2

we know that charge of 1 electron = 1.6*10^(-19)
1 C of charge = 1 electron
1 C of charge = 1/(1.6*10^(-19))
= 6.25*10^(18) electrons
