Question

how many electrons constitute one coulomb of charge

Answer 1

We know that the a electron have charge of 1.6 × 10−19 C. then 6.65 *1018 electrons constitute a coulomb of charge. e =1.6 × 10−19 C. Total charge required 1Coulomb. the number of electrons constituting one coulomb of charge.

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
