We present the possible use of spectro-polarimetric measurements on a set of data recorded with La Palma Stokes Polarimeter attached to the Swedish Vacuum Solar Telescope. The stratification over the solar atmosphere of different physical parameters is retrieved from these data using the Stokes Inversion based on Response functions (SIR). We derive the vertical component of electric current density coming out from the stratification of the magnetic field strength and orientation of the magnetic field vector. We also found spatial and height correlation between the temperature enhancement and increase of electric current density, this could be caused by the energy dissipation stored in the magnetic field configuration.
