Electrical Conductance, Current, and Resistance

Since a number of different techniques are included under the broad term of thermoelectrometry, this discussion will be divided into three categories (1) electrical conductance, current, and resistance (2) dielectric constant and capacitance and (3) miscellaneous electrical techniques that are of interest to thermal analysis. 

Adeosun and co-workers studied the electrical conductance and other properties of molten lead dodecanoate and mixtures with lead acetate (57), do-decanoic acid (58), metal dodecanoates (59), and lead (II) oxide (60). Using the specific conductance of lead dodecanoate mixtures, they interpreted the curvature of these curves in terms of a simple dissociation theory involving lead dodecanoate (PbA2)  

Assuming that the major charge carrier is Pb2 + and that it moves by a simple activated process, the following expressions were obtained  

For the mixtures of PbA2 with Pb(C2H302)2, the values of (AH + AH/3) ranged between 47 and 50 kJ mole-1. 

The dc electrical conductivity of a number of N-(2-pyridyl)benzamide and N, N -dibenzoyl-2,6-diaminopyridine metal complexes, as a function of temperature (to 388 K) and radiation, was studied by Abou Sekkina et al. (61). Linear log versus l/T plots were obtained for all the Cu(II) and Ni(II) complexes, from which the activation energy, Ea, and other parameters could be calculated, using the expression
