conÂ·ducÂ·tivÂ·iÂ·ty. n. pl. conÂ·ducÂ·tivÂ·iÂ·ties. 1. The ability or power to conduct or transmit heat, electricity, or sound. 2. The conductance of a material. 3. Physiology The conductibility of a structure, especially the ability of a nerve to transmit a wave of excitation.
Units of Measurement. Electrical Conductivity is the ability of a solution to transfer (conduct) electric current. It is the reciprocal of electrical resistivity (ohms). Therefore conductivity is used to measure the concentration of dissolved solids which have been ionized in a polar solution such as water.nits of Measurement.
