Electrical conductivities of steady-state, three-phase (macro)emulsions formed by the top (T), middle (i.e., microemulsion, M), and bottom (B) phases of the amphiphile/oil/'water' (i.e., aqueous 10 mM NaCl) system C[sub 6]H[sub 13](OC[sub 2]H[sub 4])[sub 2]OH/n-tetradecane/water have been measured and compared with conductivities predicted by equations for different emulsion morphologies. Two temperatures were used, one above and one below the temperature of the middle-phase wetting transition. The appropriate conductivity equations, and thus the emulsion morphologies, appeared to depend on the wettability of the T-B interface by the middle phase. 17 refs., 9 figs.
