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 C6H13(OC2H4)2OH/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.
