Which unit typically represents current?

The unit that typically represents current is the ampere. Current is defined as the flow of electric charge in a circuit, measured in terms of the quantity of charge passing a point per unit time. One ampere is equivalent to one coulomb of charge passing through a given point in one second. This foundational unit is critical in understanding electric circuits and is central to various applications in physics and engineering.

In contrast, volts measure electrical potential difference, ohms measure resistance in a circuit, and joules quantify energy. Each of these units has distinct roles in the study of electricity and circuits, but it is the ampere that specifically denotes the flow of electric current.
