How does the resistance of a conductor changes
with temperature.
Answers
Answer:
As the temperature increases, the ions vibrate with greater amplitude. Because of this, the ions and the electrons are more likely to collide and the electron finds it more difficult to move through the conductor. ... Notice that the resistance of the conductor is proportional to the temperature change.
At the microscopic level, resistance is also defined as the collision of free electrons with other electrons as well as with the positive charge particles/atoms. So, when temperature of a conductor rises, mobile electrons gain high energy, due to which there percentage of collision increases. This increase in the collision rate takes the form of resistance. As the temperature increases, collision rate increases thereby increasing the resistance. Hence, this results in the change of resistance of a conductor with temperature..
