Electrical conductivity
What is Electrical Conductivity? Electrical conductivity, shown by the Greek letter sigma ($\sigma$), quantifies how easily electric current moves through a material. Its standard unit is Siemens per meter (S/m). We often talk about its inverse, electrical resistivity (rho, $\rho$), measured in Ohm-meters ($\Omega \cdot m$). Simply put, conductivity is one divided by resistivity. Many … Read more
