To find :
Number of electrons constituting 1 coulomb of charge
Given :
- Total charge = 1 C
Solution :
Point to know - Charge on 1 electron is -1.6 x 10⁻¹⁹ Coulomb
[ Note - But we will take charge of 1 electron = 1.6 x 10⁻¹⁹ Coulomb , that is magnitude only ]
➝ 1.6 x 10⁻¹⁹ Coulomb has 1 electron
➩ 1 Coulomb charge is in = 1 ÷ ( 1.6 x 10⁻¹⁹ ) electron
➩ 1 Coulomb charge is in = 10¹⁹/1.6 electron
➩ 1 Coulomb charge is in = 10× 10¹⁸/1.6 electron
➩ 1 Coulomb charge is in = (10/1.6) × 10¹⁸ elecrton
➩ 1 Coulomb charge is in = 6.25 × 10¹⁸ elecrton

ANSWER : 6.25 × 10¹⁸ elecrton
