I'm trying to characterise a resistor's temperature at equilibrium when I know the voltage on it and the ambient temperature. I have a few ways to measure but I get mixed results, so I'm searching for a theory to compare to. I'm a second year physics and EE student and I haven't done thermodynamics yet, so I'm kind of lost.
I can use curve fitting to find hard-to-reach constants like its heat capacity. I can also control the ambient temperature and the power supplied to it. In the measurements it seems like the temperature is rising exponentially (with a negative time factor).
Is there an equation or some models I can dive to?
Thanks in advance.
