Question

Calculate the number of electrons constituting half coulomb of charge​

Answer 1

Answer:

An electron is a subatomic particle commonly represented as e– or e. It possesses negative polarity. An electron inherits the properties like – Charge, Mass, Spin, etc. The values of the electron simply the value of the charge of an electron, the mass of the electron, and a quantum mechanical property- spin of the electron along with corresponding units.

We know that the charge on an electron is negative, and it is 1.6⨯10-19 coulomb.

Need to calculate the number of electrons constituting one coulomb of charge.

e = 1.6 × 10-19 C

Total charge required for 1Coulomb.

∴ q = 1C……….(1)

The formula to calculate the charge is

q = ne

where

q = charge

e = number of electrons

n = q/e……….(2)

Substituting equation (1) in equation (2), we get

n = 1/(1.6 × 10-19)

n = 6.25 × 1018 electrons ≅ 6 × 1018 electrons

So 1 Columb of charge contains 6 × 1018 electrons.
