In the present work, our investigation is carried out to study on the optical- electrical properties of multi-component system of Mefenamic acid (MA), Ethanol+Poly Ethylene Glycol (E+PEG). Mixtures of these molecules exhibit a smectic-A, smectic-C, smectic-E and smectic-B phases sequentially when the specimen cooled from its isotropic phase. These phases have been characterized by using microscopic technique. The temperature variations of optical-density and ultrasonic measurements and electrical conductivity have been discussed.
