Current-induced electrical resistance was investigated for zero applied magnetic field in long superconducting strips of tin 100 to 200 $mu$m wide and up to a few $mu$m thick. Self-heating effects were observed similar to those reported recently by Skocpol, Beasley, and Tinkham (SBT) for ''one-dimensional'' tin microbridges with dimensions much smaller than those of our samples. Results agree well with the one-dimensional SBT hotspot model for long microbridges. In the presence of an inductive load, relaxation oscillations can be observed resulting from the negative differential resistance region in the V-I characteristic. (auth)
