North Atlantic Current in the south and 20 Sv as it crosses the Mid-Atlantic Ridge. It reaches speeds of 2 knots near the North American coast. Directed by topography, the NAC meanders heavily, but in contrast to the meanders of the Gulf Stream, the NAC meanders remain stable without breaking off into eddies. The colder parts of the Gulf Stream turn northward near the "tail" of the Grand Banks at 50°W where the Azores Current branches off to flow south of the Azores. From there the NAC flows northeastward, east of the Flemish Cap (47°N, 45°W). Approaching the Mid-Atlantic Ridge, it then turns
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
