Question

What is thermal resistance of a conductor? On what factors does it depend?

Answer 1

The thermal resistance of a body is a measure of its opposition to the flow of heat through it. It is defined as the ratio of temperature difference to the heat current. Thermal resistance of a body depends on length and area of cross-section of the conductor.

Resistance of a conductor depend on four factor

1.Temperature

2.Length

3. Thickness ( crossectional area of wire)

4. Fourth is depend on conductivity of the material that is used .

Some examples of good conductive material are : Copper , Silver etc .
