Question
What effect does a hotter temperature have on resistance?
- No effect
- Stays the same
- Increases resistance
- Decreases resistance
Hint:
Resistance of a material is directly proportional to the temperature.
The correct answer is: Increases resistance
- When the temperature increases the resistance of the conductor also increases.
- It is because, when heat flow in the conductors increases the movement of free ions and radicles present in the conductor also increases which in turn will increase the resistance of the conductor.
