OK,
Strange question, but I have a very practical, if simple, need to apply the Law.
I need to heat a copper wire to several hundred degrees and I am trying to figure out a rough voltage and amperage to push through it. I am staring at
http://www.epanorama.net/documents/wiring/wire_resistance.html
trying to figure out what I need to push through 10 or 12 gauge 2m copper wire to get the heat I need.
For an explanation of what I am trying to do, see below:
______________________
stupid previous owner used construction adhesive to glue paneling to 200 year old hand plastered walls. Ripping to panels off simply rips the plaster off of the wall. The adhesive fails rapidly under moderate heat from a torch, but I can't get the torch behind the panels. Bad alternative plan consists of a using a car battery charger to push 6-12 A at 12V until the copper is nice and hot and then pull the wire down behind the panels to cut through the adhesive.
_______________________
The obvious approach is to experiment and see what happens, but I figured I should be applying a very basic scenario of Ohms law, and thought you guys (gals?) might be able to help me out under the assumption I fail.
suggestions appreciated
