NEET Physics Resistivity and Temperature Multiple Correct Question
Temperature dependence of resistivity ρ(T) of semiconductors, insulators and metals is significantly based on the following factors : (1) number of charge carriers can change with temperature T (2) time interval between two successive collisions can depend on T.
Both 1 & 2
Neither 1 nor 2
Correct Answer
Detailed Explanation
In semiconductors, the number of charge carriers increases with temperature, while in metals, the collision time affects resistivity.
