In which unit is the current flow in an electrical circuit measured?

The flow of current in an electrical circuit is measured in amperes. This unit quantifies the amount of electric charge that flows through a conductor over a given period. Specifically, one ampere represents one coulomb of charge passing through a point in a circuit in one second. Understanding this measurement is crucial for assessing how much current is being utilized or required in various electrical applications, such as motors, lighting, and other electrical devices.

The other units provided serve different purposes in electrical systems. Watts measure electrical power, which is the rate of energy consumption or generation; volts measure electric potential difference, which is the force that drives the current through a circuit; and ohms measure resistance, which indicates how much a material opposes the flow of electric current. Hence, amperes is the correct unit for measuring current flow.
