Control Of Joule Heating Effect In Tungsten Wire.

[Althalu5]

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?
