Question

calculate the number of electrons constituting 1C of charge.(charge on an electronis 1.6×10^-19C)​

Answer 1

We know that the a electron have charge of 1.6 × 10−19 C

Then 1 coulomb of charge contans = 1/(1.6*10^-19)=6.25*10^18 electrons

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
