Control Of Joule Heating Effect In Tungsten Wire.

  1. Oct 3, 2011 #1
    How can I accurately control the Joule Heating effect of a length of Tungsten wire to certain temperature ranges? The tolerance would have to be no more than a maximum of +/- 2°C.

    Would I require alternating or direct current and/or any other associated instrumentation?

    I have little or no background in physics but I cannot seem to find the answer anywhere.

    Any help would be most appreciated.

    Do you have anything that controls the amount of current/voltage across the wire?
