why temperature causes resistance?

Question

please give me reason with atomic funtion theory.
i knew that , temperature vibrate the resistive element in resistor so it increase resist, however other elements also vibrated due to temperature.
why other element not reduce resistance?

Answer 1

The reason why any material has resisitance is because electrons collide with atoms while they flow through the wire. If the temperature keeps rising, the atoms in the wire vibrate more as they absorb thermal energy. This increase in vibrations causes the frequency of the collisions between the electrons and atoms to increase, therefore inmcreasing the resistance.

However, if you're talking about superconductors, as long as the temperature of the material is kept below the critical temperature (the temperature at which there is zero resistance) any increases in temperature will not reduce the current.

Answer 2

It all depends on the atomic structure of the Conductor.
When Temperature energy is added to atoms,it causes the atoms to expand. As the result of this expansion the space between the atoms gets narrower and constricting the motion of the electons whih cause resitance ot the motion.
This resistance is measured in terms of inverse velocity Units.

You need a crash course in the English language before you ponder the 'imponderables' of Physics
