With increase in temperature, the resistivity of a conductor
Question
With increase in temperature, the resistivity of a conductor
Solution
With an increase in temperature, the resistivity of a conductor generally increases. This is because as temperature rises, the atoms of the conductor start to vibrate more. This increased vibration leads to more frequent collisions between the electrons and the atoms, which increases the resistance to the flow of electrons (current). Therefore, the resistivity of the conductor increases.
Here are the steps to understand this:
- When the temperature of a conductor increases, the atoms in the conductor start to vibrate more.
- These vibrations cause more frequent collisions between the electrons (which carry the current) and the atoms of the conductor.
- These increased collisions make it more difficult for the electrons to flow, which increases the resistance to the flow of current.
- This increase in resistance is observed as an increase in the resistivity of the conductor.
So, in summary, with an increase in temperature, the resistivity of a conductor generally increases.
