The number of electrons constituting one coulomb of charge can be calculated using the elementary charge, denoted as “e,” which is approximately equal to 1.602 x 10^-19 coulombs.

To find the number of electrons in one coulomb, we divide one coulomb by the elementary charge:

Number of electrons = 1 coulomb / elementary charge

Number of electrons = 1 C / (1.602 x 10^-19C)

Number of electrons ≈ 6.242 x 10¹⁸ electrons

So, one coulomb of charge is approximately equivalent to 6.242 x 10¹⁸ electrons.

This calculation is based on the fundamental charge of an electron and provides a precise understanding of the quantity of electrons needed to constitute one coulomb of charge. It is a fundamental concept in electricity and is widely used in electrical engineering and physics.
