We investigated pulsed and DC I-V characteristics of a variety of resistive oxides. Examples of pulsed, compared with DC characteristics, are shown for samples of La_{1.2}Sr_{1.8}Mn_2O_7 (a double layer manganite), Pr_{2/3}Ca_{1/3}MnO_3 and Bi_{1/2}Sr_{1/2}MnO_3 (charge-ordered manganites), Sr_2FeMoO_6, Sr_2CrWO_6 and Ba_2MnReO_6 (double perovskites). For pulsed measurements, single pulses in the ms range were applied. For short-rise-time square pulses, the Joule heating is negligible, as long as the response remains independent of time. The DC I-V characteristics were measured up to current runaway in the negative resistance regime;Δ T never exceeded a fraction of a degree. In most cases the DC characteristics mask a perfectly ohmic or moderately non-ohmic conductivity obtained by pulsed measurements. This demonstrates that the widely used DC I-V measurements in the high current regime are frequently misleading.
