Starting from the classical equation of motion for a mesoscopic capacitance coupling circuits,the quantum fluctuations of charge and current of the circuits in a displaced squeezed Fock state are investigated.It is found that the quantum fluctuations of charge and current in each component circuit depend on the device of the two loop circuits and squeezing parameters,while the fluctuation does not depend on displacement parameters.
