Physical nature of equilibrium of current-carrying filaments is studied on the basis of Einstein equations of General Relativity. Considering a conducting filament as an element of the structure of Universe, one has to take into account both electromagnetic and gravitational interactions of charges. The energy of the proper electromagnetic field, stored in the current channel, contributes to the gravitation field of the system together with the energies of individual charges. Depending on the relation between the parameters of a filament there are two different physical situations of weak and strong current. In both limiting cases of weak and strong current we derive analytically energy balance condition (a generalization of famous Bennet relation), valid for arbitrary equation of state of matter within a filament. Even if the current is small the relative motion of electrons with respect to ions, connected with the current, results in additional gravitation attraction of these two subsystems. This relativistic effect does not exist within Newtonian approximation. In the limit of high current energy balance relation displays common physical nature of gravitational collapse and electromagnetic one. Boundaries of equilibrium domain determine limiting parameters of a filament: maximum energy per unit length stored in the magnetic field is 0.927.1048 erg/cm, limiting current is 0.94.1025 A, and maximum gravitational mass per unit length is 0.81.1028 g/cm.
