Electrical current is measured in amperes, which is often abbreviated as "amps." The ampere is defined as the amount of electric charge passing a point in a circuit per unit time. More specifically, one ampere represents one coulomb of charge moving past a given point in one second.

The other units mentioned are related to different electrical properties: watts are used to measure power (the rate of energy transfer), ohms measure resistance (the opposition to the flow of current), and volts measure electric potential or electromotive force (the difference in electric potential between two points). Understanding this distinction helps clarify how electrical systems operate and how current interacts with voltage and resistance in circuits.
