The basic components needed for the exploding wire method are a thin conductive wire and a capacitor. The wire is typically gold, aluminum, iron or platinum, and is usually less than 0.5mm in diameter. The capacitor has an energy consumption of about 25&nbsp;kWh/kg and discharges a pulse of charge density 10⁴ - 10⁶ A/mm²,<ref name=prepnano>{{cite journal |last1=Kotov |first1=Yu |title=Electric explosion of wires as a method for preparation of nanopowders |journal=Journal of Nanoparticle Research |date=2003 |issue=5 |url=http://cms.springerprofessional.de/journals/JOU=11051/VOL=2003.5/ISU=5-6/ART=5140986/BodyRef/PDF/11051_2004_Article_5140986.pdf |deadurl=yes |archiveurl=https://web.archive.org/web/20141215001933/http://cms.springerprofessional.de/journals/JOU=11051%3D11051/VOL=2003%3D2003.5/ISU=5%3D5-6/ART=5140986%3D5140986/BodyRef/PDF/11051_2004_Article_5140986.pdf |archivedate=2014-12-15 |df= }}</ref> leading to temperatures up to 100,000[[Kelvin|K]].
