The SI unit of conductivity is S/m and, unless otherwise qualified, it refers to 25 °C. More generally encountered is the traditional unit of μS/cm. The commonly used standard cell has a width of 1 cm, and thus for very pure water in equilibrium with air would have a resistance of about 10 ohms, known as a megohm. Ultra-pure water could achieve 18 megohms or more. Thus in the past, megohm-cm was used, sometimes abbreviate… Webfilled electric conduction using unfilled part of VB) Alkaline earth metal (divalent, 12 e’s) good conductors because their valence band overlaps another band Conductivity of …
