Asked in CBSE AIPMT 2002 · Temperature dependence of resistance

Answer: (1) increase in temperature

Step-by-step solution

Specific resistance (resistivity) is a property of the material; it does not depend on length or area.

For a conductor, heating increases lattice vibration and so electron scattering.

So its resistivity increases with increase in temperature.
