What is the unit for measuring electrical current?

The unit for measuring electrical current is indeed the ampere, commonly referred to as "amp." Electrical current represents the flow of electric charge, and the ampere quantifies that flow. One ampere is defined as one coulomb of charge passing through a conductor in one second.

It's important to understand the role of the other units listed. Volts measure electric potential or voltage, which is the force that pushes electric charge through a circuit. Ohms measure resistance, which quantifies how much a material opposes the flow of current. Coulombs are units of electric charge rather than current itself, indicating the amount of charge that flows.

In summary, the ampere stands as the clear unit for current, emphasizing the importance of understanding the different electrical concepts and their respective units.
