Question

Calculate the number of electrons constituting one coulomb of charge.(Charge on 1 electron = 1.6×10ki power 19 give me a clear answer ​

Answer 1

Answer:

• 6.25×10¹⁸ is the total number of electrons.

Explanation:

Given:-

• Charge ,Q = 1 C

• Charge on Electron ,e = 1.6×10⁻¹⁹ C

To Find:-

• Number of electrons ,n

Solution:-

As we have to calculate the number of electrons constitute one coulomb of charge .

Using Formula

• Q = ne

where,

• Q denote Charge
• n denote number of electrons
• charge of electron

Substitute the value we get

→ 1 = n × 1.6×10⁻¹⁹

→ n = 1/1.6×10⁻¹⁹

→ n = 1×10¹⁹/1.6

→ n = 6.25 × 10¹⁸

• Hence, the number of electrons is 6.25 × 10¹⁸ .

Answer 2

Answer:

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.
