Question

calculate no of electrons present in 0.1 coulomb of charge

Answer 1

Here is your answer

No. of electrons present in 1 coulomb charge= 6.25 × 10^18 electrons
So,
no. of electrons present in 0.1 coulomb charge= 0.1 × 6.25 × 10^18 electrons
=6.25 × 10^17 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
