Good to know
- Conductivity and resistivity are inverses of each other — high conductivity means low resistivity.
- Copper conducts better than aluminium at the same size.
- Pure water conducts very little; dissolved salts raise conductivity.
- Values change with temperature, so note the temperature when comparing.
Note: Resistivity = 1 / Conductivity. Mho is the old name for siemens (1 mho = 1 S).
