✦ Synopsis
The variable-range hopping expression R(T)= Ro e(T°/rl~ used to describe data for carbon and thick film chip resistors is discussed. For both kinds of resistors it was found that 1/4 ___(~ ___ 1/2, although for the thick film resistors the applicability of models originally used in doped semiconductors is still under discussion. The use of these resistors as thermometers in heat capacity measurements in the range 0.05-1.5 K is also discussed.
