Electrical conductance
Conductance is the reciprocal of resistance and is different from conductivitiy (specific conductance). Conductance is the ease with which an electric current passes through a conductor. The SI unit of electrical resistance is the ohm (?), while electrical conductance is measured in siemens (S). [Wikipedia: https://en.wikipedia.org/wiki/Electrical_resistance_and_conductance]
