Current is measured in which unit?

Current is measured in amps, which is short for amperes. The ampere is the standard unit of electric current in the International System of Units (SI). It is defined as the flow of electric charge across a surface at a rate of one coulomb per second. Understanding this unit is crucial as it directly relates to the flow of electricity in circuits, where the current indicates how many electrons are flowing past a certain point within the circuit.

The other units mentioned relate to different electrical concepts: volts measure electrical potential or voltage, ohms measure resistance in a circuit, and watts measure power, which is the rate of energy transfer. Each unit plays a distinct role in the study of electricity and circuits, but for the measurement of current specifically, amperes is the appropriate choice.
