As the temperatur
Resistance is depends on temperature. If temperature is increase, resistivity will increase. Increase in resistivity will leads to decrease in conductivity. The relation is given below.
The product of resistivity and conductivity is not depend on temperature. Because resistivity and conductivity of a metallic resistor are nullifying the change in the temperature.
If the temperature of a metallic resistor is increased, the product of its resistivity and
Conductivity may increase or decrease. Option D is correct.
