In this video, I have told you about heat conduction through a hollow sphere. The derivation is same as heat conduction through hollow cylinder and plain wall.
We applied the formula for heat conduction through hollow sphere for all the layers. Then we find the temperature difference. then we get the four equation. After adding these equations, Finally we get the value of Q.
