The electrical resistance of tungsten samples was measured under shock wave loading up to 15 GPa. The experiment was analyzed and modeled taking into account the volume-temperature and deformation components of the electrical resistance of tungsten. The relationship between the excessive electrical resistance of the deformation component and the characteristics of the absolute deformation rate of tungsten under planar one-dimensional loading is considered. Keywords: electrical resistance, tungsten, equations of state, shock waves, deformation, strain rate, hydrocode.
