With increase in temperature, resistance of a conductora)decreasesb)increasesc)may decreases or increase according to the situationd)no particular observation.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

When the temperature of metallic conductor increases, the velocity of free electronsincreases but it also cause increase in amplitude of vibration of metallic atoms (kernels) which cause some extra hindrance or resistance in the path of free electron. Hence resistance increases in investing the temperature...........if u like it then plzz upvote,,,,,,and if u want then start following me........byee and take care

Answer

As the temperature of a metallic conductor increases, the kinetic energy of the electrons of the conductor also increases
Due to this increase in kinetic energy more obstruction is offered to the flowing electrons i.e. current.
Therefore, as more obstruction is offered to the flowing electrons, the resistance is increased.

Answer

The answer b.) is correct.....B'cuz when  the temperature increases there's much more collision between the electrons....... which resists their flow.....nd'eventually increases the resistance!!!that's it!!

Answer

With increase in temperature the free electrons tend to move faster hence the collision is more the resistance increase.

Answer

Understanding Resistance in Conductors
Resistance in a conductor is influenced by various factors, including temperature. As temperature increases, the behavior of resistance in conductors can be explained as follows:

How Temperature Affects Resistance
- Conductors, such as metals, are made up of atoms that vibrate.
- At higher temperatures, these atomic vibrations increase, leading to more collisions between free electrons and vibrating atoms.
- This increased collision frequency results in greater opposition to the flow of electric current, causing resistance to rise.

Why Resistance Increases
- The primary reason that resistance increases with temperature is due to the nature of metallic bonds.
- Metals have free-moving electrons that carry charge. As temperature rises:
- The increased thermal energy causes atoms to vibrate more intensely.
- This leads to an increase in the likelihood of electrons colliding with these vibrating atoms, thereby impeding their flow.

Real-World Implications
- Many electrical devices are designed to operate within specific temperature ranges.
- For instance, in electrical circuits, higher resistance can lead to inefficiency and overheating in components, which can be detrimental to their performance and longevity.

Conclusion
In summary, for most conductive materials, the resistance increases with temperature. Therefore, the correct answer to the question is option 'B'—the resistance of a conductor increases with an increase in temperature. Understanding this relationship is crucial for designing efficient electrical systems and ensuring their proper functioning under varying temperature conditions.

Answer

As the temperature of a metallic conductor increases, the kinetic energy of the electrons of the conductor also increases
Due to this increase in kinetic energy more obstruction is offered to the flowing electrons i.e. current.
Therefore, as more obstruction is offered to the flowing electrons, the resistance is increased.

Answer

Since temperature is directly proportional to resistance of a resistor, so this happens.
