One thing that puzzles me about this method. The temperature of the A-B interface is not the same as the temperature of the A-C interface, is it? same for on the D side... How come that the circuit analysis works like this? What is the 'T' at the nodes that I am mentioning?

The instructor should have mentioned the assumptions utilized in this particular example. One of them being that all surfaces normal to the x-direction are isothermal.

What if using thermal resistivity?

@5:32 shouldn't the parallel resistance be R(b)'+R(c)' = [R(b)*R(c)]/[R(a)+R(b)]

What will be the temperature profile for this case?

Can you tell me what will be temperature profile please 🙏🏻

Please all note that temperatures in the problem are in ºC while in the solution are in ºK ...

Doesn't matter we are concerned with temperature difference so the value will remain same

this solution is wrong. Parallel resistance is calculated incorrect.

Once again errors made in this video: When summing up the total resistances, Rt = Ra + 1/ Rb + 1/Rc + Rd This will give Rt= 32.79 K/W and hence, Q = 1.68W

This is correct. The formula goes 1/Rbc = 1/Rb + 1/Rc, thus the -1 power in order to convert it back to Rbc.
