Ocean current the windthe Coriolis effect plays a role in their behaviours. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective "thermohaline" derives from "thermo-" referring to temperature and "" referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk
Drift current through a square centimeter area perpendicular to the direction of flow. (i) Drift current density J, due to free electrons is given by: formula_1 (ii) Drift current density J, due to holes is given by: formula_2 Where: n - Number of free electrons per cubic centimeter. p - Number of holes per cubic centimeter formula_3 – Mobility of electrons in formula_4 formula_5 – Mobility of holes in formula_4 E – Applied Electric Field Intensity in V /cm q – Charge of an electron = 1.6 × 10 coulomb. Drift current In condensed matter physics and electrochemistry, drift current is the
