Electrical behavior of exploding copper wire in ambient air

MO Barbaglia, G Rodriguez Prieto - Physics of Plasmas, 2018 - pubs.aip.org
This work experimentally investigates the electrical behavior of an exploding wire when the
initial energy of the system varies from 28 to 709 J. This experiment uses 50-μm-diameter,
33-mm-long copper wires. The wire is surrounded by air at normal atmospheric pressure
and temperature. The experiment monitored the current derivative, voltage between wire
ends, total visible radiation emitted, and the shadow image of the wire to study how the
electrical parameters vary as a function of initial energy. The results indicate a change in the …
