How will increasing the temperature of a solid conductor affect electric conductance?
Conductance will decrease
Conductance will increase
Conductance will not change
Can't say
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.
