Our brain waves share and are attuned to certain frequencies of the Schumann’s resonances, the ELF signals that pulsate between the Earth’s crust and ionosphere.

This has been mistaken to be a measure of resistance, which seems to become infinite at low pressures, but this is not correct. At higher pressures, the breakdown voltage increases steadily with pressure (off the right side of Figure 2) , and so does the resistance. So there is a direct relationship between breakdown voltage.

Oct 19, 2016. Other paint suppliers prefer to talk in terms of resistivity. Resistance, which is related to but not the same as resistivity, is another important electrical term that has meaning for most people. The remainder of this bulletin clarifies the relationship between these terms. It is a useful exercise because it provides.

Ohms-cm is used for measuring the conductivity of a three dimensional material such as a silicon ingot or a thick layer of a material. The term “Ohms-per-square” is used.
