Question

Calculate the number of electrons constituting ane Coulomb of charge​

Answer 1

Question:-

Calculate the number of electrons constituting ane Coulomb of charge

Answer:-

The number of electrons is 625.10¹⁶

Explanation:-

We know that ,

$\red \bigstar \ \ \boxed{ \sf{q=ne}}$

Where,

• q = charge

• n = number of electrons

• e = charge on electrons

$\sf{:\implies 1C=n(1.6×10^{-19})}$

$\sf{:\implies n=\dfrac{10^{19}}{1.6}}$

$\sf{:\implies n=625.10^{16}\:electrons}$

Hence, the number of electrons is 625.10¹⁶

Answer 2

Explanation:

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

We 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
