Question

Calculate no of electrons constituting 1C of charge

Answer 1

We can solve this by unitary method.
1.6 × 10^(-19) C is the charge of 1 electron.
1 C is the charge of 1/(1.6×10^(-19)) = 6.25 × 10^18electrons.

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
