Abstract: Electric current in the ultracold highly collisional plasma was considered in the work by the method of molecular dynamics. The current is caused by the electric field applied to plasma. Calculations are made for different values of the collisional parameter. Plasma conductivity was determined from the ratio of current and electric field. Comparison with the results obtained by other methods was performed. The difference from the results obtained earlier on the basis of the analysis of the diffusion coefficient and the autocorrelation function of the current is discussed.

Keywords: molecular dynamics, collisional plasma.
