One coulomb of charge is equal to what?

One coulomb of electric charge is defined as the amount of charge that is transported by a constant current of one ampere in one second. The charge of a single electron is approximately 1.6 x 10^-19 coulombs. To determine how many electrons make up one coulomb, you can divide one coulomb by the charge of a single electron.

Calculating this leads to the following:

1 coulomb / (1.6 x 10^-19 coulombs/electron) = 6.24 x 10^18 electrons.

This calculation shows that one coulomb is equal to 6.24 x 10^18 electrons, making this the correct answer. Understanding this relationship is crucial for electrical computations, as it directly connects charge to the number of electrons in conductive materials.
