An electric current is a flow of charged particles, such as electrons or ions, through an electrical conductor or space, defined as the net rate at which electric charge flows through a surface. The cited article explains that the moving particles are called charge carriers, which may be of several types depending on the conductor: in electric circuits they are often electrons moving through a wire, in semiconductors they can be electrons or holes, in an electrolyte they are ions, and in plasma they are ions and electrons. It notes that in the International System of Units electric current is expressed in amperes. Units such as the ampere are grouped under this quantity.

Quantity Measured By Unit
Ampere, Units Entity-backed identity for the quantity-measured enum value this unit already carries, resolved to a science concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The quantity-measured fact itself stays on the unit unchanged.
