● jingle · one word, three constructs Nearest construct by meaningresistancecompare the meaningsEvery construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to current is resistance.
Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

The rate at which electric charge flows past a point in a conductor, defined as I = dq/dt and measured in amperes, one coulomb of charge per second. Ohm fixed the empirical law in 1827: in a metallic conductor the current is proportional to the voltage across it and inversely proportional to its resistance, V = IR. The referent is charge in motion through a circuit, and the quantity is a flux, something that can be zero, steady, or alternating, with a magnitude and a direction along the wire. It is a physical rate set by a field and a material, owing nothing to water or to trade.[1][2]
A continuous, directed movement of seawater, driven by wind, by the Earth's rotation, and by differences in temperature and salinity, carrying heat and mass across ocean basins. Stommel explained in 1948 why the wind-driven gyres intensify on their western edges, which gives the swift Gulf Stream its form, and Broecker's 1991 great ocean conveyor named the slow global loop that the thermohaline circulation drives. The referent is a body of water in motion, described by a velocity field and a volume transport on the order of tens of millions of cubic metres per second. It is a fluid flow in the ocean, sharing only the word with a wire or a balance sheet.[3][4]
The part of a nation's balance of payments that records its trade in goods and services, its net income from abroad, and its net current transfers, summed over a period such as a quarter or a year. The IMF's Balance of Payments and International Investment Position Manual defines the account and its place in the wider ledger, while Obstfeld and Rogoff's intertemporal approach reads a current-account surplus or deficit as a country lending to or borrowing from the rest of the world. The referent is a country's external transactions across time, an accounting record kept in currency, not a physical flow. A surplus here is a claim on foreigners, not a rate of charge and not a movement of water.[5][6]
