Question

How much electrons to make one coulomb charge ?

Answer 1

Hi there!

We know that the a electron have charge of 1.6 × $10^{-19}$ C

∴ e =1.6 × $10^{-19}$ C

Total charge required 1 Coulomb :

∴ q = 1C

Since q = ne

⇒ n =q/e

⇒ n =  1/1.6 × $10^{-19}$

⇒6.25 × $10^{18}$

⇒6 × $10^{18}$ electrons.

[ Thank you! for asking the question. ]
Hope it helps!

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
