As we learnt

 

Dependence of electric conductance -

 

The electric conductance depends on:

1. The nature & structure of material.

2. The number of valence electron per atom.

3. Temperature (it decreases with increase of temperature)

-

 

 

 

Upon increasing temperature the conductance of a solid conductor decreases because higher temperatures allow greater vibrations of atoms thereby restricting the flow of electrons.
