Deep Water Currents--Thermohaline Circulation
Deep Water Currents--Thermohaline Circulation

Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

Like a river current is the flow of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.

Solar Heating Cause Water to Expand
Solar Heating Cause Water to Expand

Active solar heating systems use solar energy to heat a fluid -- either liquid or air -- and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat.

Surface Currents--Surface Circulation
Surface Currents--Surface Circulation

First, a surface current is an approximation. Really, only volume currents exist. In metallic antennas, the surface current is an actual electric current that is induced by an applied electromagnetic field.

The Primary Forces are:

Electric circuits can be series or parallel. You need to know the symbols we use to draw circuit diagrams. An ammeter measures electric current, in amps, by measuring how much charge is flowing in the circuit.
