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?
 
I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
