Which unit would you use to express current flowing through an electrical circuit?

The correct unit for expressing current flowing through an electrical circuit is the Ampere. Current is a measure of the flow of electric charge in a circuit, and the Ampere, often abbreviated as "Amp," quantifies this flow. One Ampere is defined as one coulomb of charge passing through a point in the circuit in one second. This unit is fundamental in electrical engineering and is essential for understanding how current interacts with voltage and resistance in circuits.

Other units related to electricity include Volts, which measure electrical potential or voltage; Watts, which measure power (the rate of doing work or the rate at which energy is transferred); and Ohms, which measure resistance. These units are interconnected through Ohm's Law, which states that current (in Amperes) is equal to voltage (in Volts) divided by resistance (in Ohms). Understanding this relationship is crucial for analyzing and designing electrical circuits, making the Ampere a key unit for representing electric current.
