What unit of measurement is equal to a flow of one coulomb per second?

The unit of measurement that corresponds to a flow of one coulomb per second is known as an ampere, commonly referred to as an amp. This unit quantifies the rate of electric charge flow in a circuit. Specifically, if one coulomb of charge passes through a conductor in one second, the current is defined as one ampere.

To provide some context, a volt is the measure of electrical potential difference, which represents the energy per unit charge available to cause the flow of electrons. An ohm measures electrical resistance, indicating how much a material opposes the flow of current. Meanwhile, a watt measures electrical power, representing the rate at which electrical energy is consumed or produced. Understanding these distinctions is essential in electrical and electronic applications, making it clear why the correct choice in this scenario is indeed the ampere.
