Impedances are measured inside a container filled with only water, and filled up stationary particles by impedance spectroscopic method. The method uses alternating current with the renge of from 1kHz to 2MHz. An equivalent circuit from the relation ship between frequency and impedance is obtained by using the complex spectroscopic impedance method. The aim of this research is to investigate whether the resistance components such as resistances of a particle itself and water itself, a resistance of a particle interface, a resistance of a electrode interface are separable. Resistance particle is larger than the resistance of water. As, the distance between electrodes is increased, the resistance is increased. Because particle interface resistance is the capacitance, as the distance between measurement electrodes are increased, resistance decreased inversely. The electrode interface resistance is not concerned between electrodes, however both conditions become almost fixed values.
