Hello, I have a problem!

1- What is application of this circuit? What does it do?


2- Simulate this circuit in a simulator software and by determine correct values for resistors, show heat losses (H) is nearly constant.

3- Calculate H analytically (manually) (voltage division) and compare with part 2 in a software.
Hint:

(Comparator)


4- By proper ratio selection for resistors, show sensitivity of heat losses (H) with respect to thermal resistance (Rt) is almost zero.

I suggest you take this to the EEVblog Electronics forum (not that they are all that friendly to doing your homework for you, either). This site mostly revolves around safety and high quality in electricians' work, not electronics.

We can have a conversation about question 1.

When do you think you might have a temperature sensor that allows you to know the temperature (once calibrated), and the actual thing you can measure is a small resistance that you would need a Wheatstone bridge.

Write the equations for the circuit in your brige circuit. The output voltage is not linear with a change of Rt, but close for small changes.
