Question

Physics:
calculate the number of electrons in 1 meu C​

Answer 1

Calculation

The number of electrons in 1 coulomb C.

charge of electron is = -1.6⨯10-19 coulomb.

( we give - because it is always denoted by negative because electrons are negative).

Let's find the number of electron in 1 coulomb charge.

= 1.6 × 10-19 C

Charge required for 1 coulomb,

q = 1C

__________________________

q = ne ( the formula to calculate the charge)

let q be the number of charge

E be the charge

_________________________

n=q/2

n = 1/(1.6 × 10-19)

n = 6.25 × 1018 electrons ≅ 6 × 1018 electrons

So 1 Coulomb of charge contains 6 × 1018 electrons.
