We present here the response of a lipid water dispersion to an applied ac field. The electrical study of the system shows that the conductance increases with the applied bias. However with increase in the frequency of the signal the variation of conductance is less pronounced. To explain the variation of the conductance at various frequencies, we have employed the effective medium approach. The results match with the experimental values to a good approximation.
