Question

explain the dependence of resistance and resistivity on temperature

Answer 1

Answer:

resistance depends upon following:

1)length of wire

2)area of cross section

3)temperature

4)nature of material

b) on increasing temperature resistivity also increases

Answer 2

Answer:

The resistivity of a material depends on temperature. It increases with the increase in temperature and decreases with the decrease in temperature. Thus, the resistance of a material also increases or decreases with the increase and decrease in temperature
