Starting from the equation for the classical motion of a nondissipative mesoscopic capacitance coupled circuits with source,we have studied the quantum fluctuations of the charge and current in the eigenstate of the coupled circuits and in the squeezed vacuum state,respectively.The results show that the quantum fluctuations in the two circuits are correlated with each other.
