Resumen:
The linear temperature dependence of the electrical resistivity has been taken
to be one of the characteristic features of the ceramic superconductors.
Measurements of the electrical resistance of the La-Sr-Cu-O system in a wide
temperature range show that the previous statement is only an approximation
valid for some values of the Sr concentration.
