In what unit is electrical current measured?

Electrical current is measured in Amperes, commonly referred to as "amps." This unit quantifies the flow of electric charge in a circuit. Specifically, one ampere corresponds to one coulomb of charge passing through a conductor in one second.

Understanding the distinction between different electrical units is crucial. Voltage is measured in volts, which indicates the potential difference that drives the charge through the circuit. Resistance is measured in ohms, representing how much the material opposes the flow of current. Power, measured in watts, refers to the rate at which electrical energy is consumed or produced, which is calculated as the product of voltage and current (watts = volts × amps). Thus, the correct identification of amps as the unit of electrical current is essential for comprehending basic electrical principles.
