Dielectric constants of cholesteric-nematic mixtures have been measured by a bridge method. The liquid crystals used were MBBA with a small amount of cholesteryle nonanoate (CN) in the weight ratios ranging between 99.8: 0.2 and 99.0: 1.0. The texture of the cholesteric-nematic mixture consists of a single layer of filaments or small uniformly densely packed spherulites embedded in homeotropic matrix. These textures have a large pitch cholesterics. The origin of the texture depend on the ratio of the pitch to thickness of the cell and applied electric fields. As the result of measuring the dielectric constants in the case of spherulitic and filament textures, it is qualitatively explained that spherulitic domains do not completely Grandjean textures, but a randam molecular alignment of focal conic textures.
