This article presents the results of an experimental study of electrical impedance in a model cell through which the air flow containing aerosol particles of the 10% sodium chloride solution generated by an ultrasonic nebulizer passes. The active and capacitive components of admittance were determined at different values of alternating current frequency, flow rate and aerosol atomization intensity. Measurement results were compared with the most probable electrical conductivity models. An equivalent electrical circuit in the form of a parallel RC - circuit, which corresponds well to the obtained frequency dependences of impedance magnitude and phase shift angle, is proposed. In addition, a linear regression model describing the dependence of the impedance module logarithm on two parameters of the flow of aerosol particles at different electrical current frequencies is developed.
