Question

Define resistance and resistivity and also give the relation between them. Explain the dependence of resistance on
temperature
​

Answer 1

Answer:

Resistivity decreases with the decrease in temperature and increases with the increase in temperature. Thus, from the above relation we can say that the resistance of a material also increases or decreases with the increase and decrease in temperature.

Answer 2

Answer:

Resistivity decreases with the decrease in temperature and increases with the increase in temperature. Thus, from the above relation we can say that the resistance of a material also increases or decreases with the increase and decrease in temperature.
