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 same direction as the electric field, but the resulting conventional current points in the same direction as the electric field in both cases. If an electric field is applied to an electron in a vacuum, the electron will accelerate faster and faster, in approximately a straight line. A drift current looks very different than that up close. Typically, electrons are moving randomly in all directions (Brownian motion), frequently changing direction when they collide with grain boundaries or other disturbances. Between collisions, the electric field subtly accelerates them in one direction. So over time, they move at the drift velocity on
