The complex dielectric spectroscopy has been measured as a function of frequency range: 50Hz to 1MHz. at room temperature for a technologically important ferroelectric liquid crystal mixture in the different phases. The significant contribution of conductance effect at lower frequency side in measured data has observed. Contribution of conductance in dielectric permittivity and dielectric loss due to impurity influence the materials. The dielectric parameter as a function of temperature and result showed Debye- type dispersion.
