Calculate the number of electrons constituting one coulomb of charge.

Q. Calculate the number of electrons constituting one coulomb of charge.

 

Answer:- 

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
⇒6.25×1018
⇒6×1018 electrons.
