What's the resistivity of Ni/NiO????
Surely the whole point would be to create a current through the Ni? Ni is a metal and as such is a reasonable conductor. As a powder it would be less than a solid, but it also has lots of parallel paths. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
