A Hydrodynamic Explanation for the Anomalous Resistance of Exploding Wires
Wires exploded in air with current densities from 2.5 · 107 amp/cm2to 1.3 · 108 amp/cm2 exhibited a “resistance anomaly,” i.e., the resistance was not a unique function of the electrical energy deposited in the wire but depended upon the rate of energy deposition. The experiment was repeated in nonconducting environments with densities of 1 and 2 g/cm3. The resistance vs energy curve was affected by the greater confinement of these environments in the same way as by faster rates of energy input. It is proposed that inertial confinement of the wire may account for the resistance anomaly.
