Heat Current, Temperature Gradient, Thermal Resistance & Conductivity Thermodynamics & Physics 

This is a gift for JEE students!!!

I love your way of teaching . Thank you man . I wish best. Keep it up

I really wish u get more subscribers. Your way of teaching is amazing

You saved my ass many times already. Thank you!!

You are such a blessing ❤🎉

Wonderful Heat Transfer lecture ! ! !

Exactly what I needed. Thanks!

Thank you... this video is very useful.

9:01 hey there i think thermal resistance is l/kA u forgot cross sectional area

For the first and second problems, it is not specified that it’s a steady-state conduction, as it would be more logical that the metals change temperature as there is a heat exchange between them. This was probably assumed, but it would be nice to have it explicitly said (the resolution was confusing without knowing that fact).

Thank you for the video and I have a question. Isn't the thermal resistance in this particular aluminium rod represented by the length divided by the thermal conductivity times the area(L/(k*A))? It does seem logical when the area gets bigger, the resistance becomes smaller. I learned that in school and wanted to check if it is right.

Thanks for the video 👍

Can someone tell me at 14:53 why and is it viable to consider the heat current equal for the both sides. I mean the length and temperatures are different but still can we consider them equal?

thermal resistance is x/ka?

Yes this time it was good....but plz u can take it to a more difficult level...plz..

Why is A just .05 opposed to (Pie)R^2?

Thank you sooo much loveyou

Thx

Hey bro I really wish to know about you what are you doing ? Is this is your full time job?

Can someone explain why 160 is the steady state temp?

Hey thermal resistance =l/KA
