The work presents results of the research on the relations between temperature and resistance relaxation times of thin films of the YBa₂Cu₃O₇₋x superconductor deposited on substrates with different thermal conductivity (SrTiO₃, MgO, Al₂O₃) and the duration of optical and current pulses (ranging from 5ns to 1ms) and the temperature level of the superconductor film. The research was conducted by means of the numerical modelling method of the resistance response in the superconducting element. The research findings can be used for developing thin-film structures of switching elements in order to optimize the process of selecting materials and the film thickness adjusted to working modes of these elements.
