Web4 Earth return current, AC signals and capacitance 4.1 Capacitance effects Most people know that an electric circuit has to be completed to allow a current to flow. So how can a low powered signal source at the surface make a detectable current flow in a properly insulated buried conductor? The voltages available are obviously quite incapable of WebJan 1, 2016 · A sea earth at the BU provided the return current path for the Guam branch. Many modern submarine cable systems connect more than three landing points (terminal stations) using several branching units. This type of cable system allows many cities and communities to be cost-effectively connected. Soil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for finding the best location of a transmitter working on low frequiencies (VLF, LF, MF and lower shortwave) as such radio stations usually use ground as counterpole. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to desig… how do white blood cells fight pathogens
