How will increasing the temprature of a solid conductor affects electric conductance ?
Conductance will decrease
Conductance will increase
Conductance will not change
can't say
As we have learned
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 the temprature the conductance of a solid conductor decreases because higher temprature allow greater vibration of atom there by restricting the flow of electrons
