Abstract: The voltage and current of an exploding wire before its complete evaporation was obtained experimentally, and the variation of wire resistance and other parameters were calculated based on the experimental results. Bennett and Hobsons models were applied in simulating the resistance variation under the experimental parameters. The comparison between the experimental and simulated results shows that these two models are useful to guide the practice. These two models are both effective before the complete evaporation of the wire and under certain initial voltages of the capacitor. When the initial voltage of the capacitor is higher, the energy deposition velocity is faster, the time needed for the wire to melt and vaporize is shorter, and there lies a maximum resistance of the wire during its electrical explosion.
