Question

For a metallic wire, the ratio Vli (V = the applied potential difference, i = current nowmg)
1) Increases as the temperature rises
2) Independent of temperature
3) Decreases as the temperature rises
4) Increases or decreases as temperature rises, depending upon the metal​

Answer 1

Answer:

option 1 is correct

Explanation:

coz in metals as temperature increases vibrations increase in molecules hence resistance is more

Answer 2

Answer:

who is the first right answer
