Alternating current methods

Conductivity measurements were carried out by an alternating current method using 1 kHz, and measurements were taken at a current density in the range of 2,2-270 mA-cm 2. Six samples of each formula were... 

Whereas with potential step techniques, 2 = ktm, with alternating-current methods, 2 = k/v, and with RDEV, 2 = kb1 jD, where the symbols are as defined in Chapter E) Full treatment of the diffusion-reaction problem is provided in Section 6.2.1. 

The techniques and apparatus which have been developed to measure electrolytic conductivities in nonaqueous solutions have been adapted from aqueous conductivity measurements with some modifications. Direct current measurements suffer the limitation of requiring reversible electrodes - a serious limitation in nonaqueous solvents. Although this problem can be circumvented U in some instances, virtually all precision conductance data have been taken using the alternating current method. General descriptions of this method are given in several sources. 2>3)... 

Experimental Procedure.—The measurements were made by the Franck4 modification of the Rutherford alternating current method, used by...
