Control Of Joule Heating Effect In Tungsten Wire.

AI Thread Summary
To accurately control the Joule Heating effect of Tungsten wire within a tolerance of +/- 2°C, precise regulation of current and voltage is essential. Both direct current (DC) and alternating current (AC) can be used, but DC is typically preferred for stable heating. Utilizing a programmable power supply with feedback control can help maintain the desired temperature. Additional instrumentation, such as thermocouples for temperature measurement and PID controllers for maintaining temperature, may be necessary. Proper setup and calibration are crucial for achieving accurate temperature control.

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?

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
