What unit of electric current is defined as a flow of one coulomb per second?

The unit of electric current defined as a flow of one coulomb per second is the Ampere. This unit, abbreviated as "A," is one of the fundamental SI units and is crucial in understanding electrical circuits. When one coulomb of electric charge passes through a conductor in one second, that represents a current of one Ampere. The Ampere is significant in determining how much electrical charge is moving through a circuit, which can affect everything from the power consumption in devices to the safety of electrical systems. Understanding this unit provides a foundational knowledge necessary for exploring deeper concepts in electricity and electronics.
