The problem of monitoring the leakage of a heat carrier

In the approximation of slight inhomogeneity of a dielectric, the capacitance of a capacitor is determined. For a gas model, when the inhomogeneity of the dielectric results from the diffusion of an impurity into the interelectrode gap, the dynamics of the change in the capacitance and the current in a chain is studied as a function of the geometric parameters of the capacitor and the electrophysical properties of the impurity.
