What does the term "Coulomb" refer to?

The term "Coulomb" refers to a unit of electric charge in the International System of Units (SI). It quantifies the amount of charge that is transported by a constant current of one ampere in one second. In context, it represents a specific quantity of electrons, as one Coulomb is approximately equal to the charge of 6.242 x 10^18 electrons. Therefore, the correct choice accurately defines the Coulomb as it relates directly to the electric charge carried by electrons, making it a fundamental unit in the study of electricity and electronics. Understanding this unit is essential for electrical applications, as it helps in calculating other important electric parameters like current and voltage.
