Current

Resistance

Electric charge

The unit "coulomb" is a measure of electric charge. It quantifies the amount of electricity that is carried by a current in one second when there is a constant current of one ampere. Essentially, the coulomb represents the total number of electrons that flow through a conductor in a given time frame. Understanding this unit is fundamental in the fields of physics and electrical engineering, as it helps establish the relationships between charge, current, voltage, and resistance. The coulomb specifically relates to the concept of charge, distinguishing it from other electrical units that measure different properties, such as current or resistance.
