What is the relationship between power and temperature difference? How can you estimate power in a power vs change in temperature graph?

Question

mos1635 · Answer

can you be more specific...

anonymous · Answer

say the change in temperature is 65degs. This is an experiment used with a Thermoelectric cooler with the TEC having 2 sides with different temperatures.

anonymous · Answer

would you just work out the gradient using (y2-y1)/(x2-x1)

then use y-y1=m(x-x1)

?

anonymous · Answer

or is there some physics formula i am not aware of...

anonymous · Answer

oh yeh the current is 1mA and the resistance is 4.7ohms...but it is not as simple as using p=vi or ir=v because temperature is involved

anonymous · Answer

P= i2rT

sory
not familiar with many terms you are using
still unable to grasp the case

anonymous · Answer

Hmm. you need to know that energy loss can be given off as heat-in other words increase temperature change. There is an inverse proportionality for this case. I don't know if the graph is linear or quadratic
