RESISTANCE VARIATION OF EXPLODING WIRES

Abstract

When fine wires are exploded by discharging a capacitor, the circuit exhibits damped electrical oscillations as an L-R-C circuit; however, the resistance varies during the explosion which complicates the analysis. To date the resistance has been calculated either by integrating twice in succession the record of the rate of change of the current, or by the current-voltage method. A different approach is proposed in which the curcuit equation is differentiated with respect to time and then solved by a method similar to the WKB method. The method will be discussed, original data provided, and values of calculated resistance obtained by the double integration method will be used to indicate the validity of the solution.
