The spatial distribution of electrostatic potential between the metal planes in a thermal collision plasma at atmospheric pressure has been investigated. It has been shown that the potential requirement must be calculated with respect to the bulk plasma potential, which depends on the ionization equilibrium in the plasma. It has also been shown that the electrostatic perturbation in the plasma is detected only at distances of less than four screening lengths. Long-range perturbation is described by the bulk plasma potential. The electrostatic pressure on the plane as a function of boundary conditions has been found. The experimental results prove the existence of interaction between the planes, located in the low-temperature plasma at a distance that considerably exceeds the screening length, caused by changing the bulk plasma potential. The application of the results to a complex dusty plasma has shown the diminution of-the dust component dissipation in strongly coupled plasmas.
