Gulf Stream Gulf Stream The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean. The process of western intensification causes the Gulf Stream to be a northward accelerating current off the east coast of North America. At about , it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current,
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
